What is the magnitude of the ferrys velocity relative to the water?
A passenger walks from one side of a ferry to the other as it approaches a dock.Passengers velocity is 1.45 m/s due north relative to the ferry, and 4.40 m/s at an angle of 30.0 west of north relative to the water.
b.) What is the direction of the ferrys velocity relative to the water?
Answer: Since the person is walking from the south end of the ferry to the north end at 1.45 m/s, that implies that the ferry is moving at:
4.4 - 1.45 = 2.95 m/s at 30 degrees west of north relative to the water.

Relative Velocity?
Person A runs 8 m/s north relative to the ground. Person B passes him the ball at 12 m/s at an angle 37 degrees relative to the ground. What is the magnitude and direction of balls velocity relative to person A?
Answer: VA = velocity of person A
VB= velocity of the Ball
Now VB has tow victors as shown below
VB(x) = VB*cos37 = 9.58 m/s
VB(y) = VB*sin37 = 7.22 m/s
now to get the magnirude of VB
VB magnitude = SQRT (9.85)^2 + ( 7.22)^2 = 12.21 m/s
now we can find the relative velocity of the ball to person A:
V relative = VA-VB(y) = 8 - 7.22 = 0.78 m/s

What is his velocity relative to the surface of the ice?
A 50kg firefighter is standing on a 200kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is flat, frictionless surface. The firefighter begins to walk along the plank at a constant velocity of 2.0m/s to the right relative to the plank.
(a.) What is his velocity relative to the surface of the ice?
(b.) What is the velocity of the plank relative to the surface of the ice?
Answer: Let us try to solve the problem in the frame of reference of frozen lake
to begin with momentum was zero. Let Vf be the velocity of fire fighter in thisframe and Vp be that of plank. Obviously they will be in opposite direction. Momentum conservation gives
200 Vp=50 Vf and Vf+Vp=2 or Vf = 2-Vp or
200 Vp = 50 (2 - Vp) or 250 Vp = 100 or Vp = 100/250 = 0.4 m/s
So The velociy of firefighter with respect to lake = 1.6 m/s and that of planck with respect to lake is 0.4 m/s in teh opposite direction.

What formula to use for relative velocity in this Q?
How long does it take an automobile traveling in the left lane at 60.00 km/h to pull alongside a car traveling in the same direction in the right lane at 40.00 km/h if the cars’ front bumpers are initially 100 m apart?
I know it is a relative velocity and acceleration problem but I do not know how to approach the problem. The question says solve for t (time) but I don’t know how to do that. Is there a relative velocity formula with time as a variable?
Answer: Since the cars are 100 meters apart, the question boils down to how long does it take to go 100 meters at 20km/h
time = distance / speed
t = .1km / 20 km/h = .005hours = .3min. = 18 seconds

What are the magnitude and direction of the hawks velocity relative to the ground?
You are in a hot-air balloon that, relative to the ground, has a velocity of 6.2 m/s in a direction due east. You see a hawk moving directly away from the balloon in a direction due north. The speed of the hawk relative to you is 1.8 m/s. What are the magnitude and direction of the hawks velocity relative to the ground?
Answer: Assuming that the hawk's direction is relative to the balloon. Then we have a vector sum of (6.2,0) + (0,1.8) = (6.2,1.8). Magnitude = 6.456 m/s, angle = 16.189 deg = 16.189 deg N of E.

what is the difference between relative velocity and resultant velocity?
calculate resultant velocity and relative velocity when the two persons are moving in same direction as well as in opposite direction.
Answer: Similar question I had answered earlier also, but now I have got a creative way of answering it. The resultant velocity is the velocity of the object with respect to the third frame of reference. Suppose a bird or a plane is moving with respect to the air around it with some velocity V. Suppose the wind is moving with velocity V0 with respect to the ground. Then with respect to the ground the "resultant" velocity of the bird or plane will be V+V0= V' say. Now if we know V' and V0 both with respect to the ground and want to know what is V of the bird or plane with respect to the air, then it is relative velocity V = V'-V0.
For the specific problem you have asked the relative velocity of second man with respect to the first is V2 - V1 and there resultant velocity is V1 + V2 but it does not seem to have any special significance. Here I have considered V1 and V2 as vectors. If they are speeds then the answer for relative speed id V2- V1 if they move in the same direction and V1+V2 if in opposite direction but both are relative velocities, do not go by + or minus sign here.

What is the relative velocity of the airplane on the surface of the earth?
an airplane pilot tries to fly directly east with a velocity of 800.0 km/h. If a wind comes from the southwest at 80.0 km/h, what is the relative velocity of the airplane to the surface of earth?
OK i know the answer is 858 km/h, 3.8 degrees N of E but Im not sure how to get that answer and what equations to use.
Please could someone help me figure this out?

What is the Equation for relative velocity?
what equation would you use when figuring out relative velocity? so if you had a cyclist riding due west at 30m/s and he felt a breeze on his face at 32m/s from W 20 degrees N what would be the velocity of the breeze relative to the ground. i can do all the math i just need to know the format to put it into.
Answer: relative velocity is the difference between two velocities. They may not be exactly opposing each other and in the case of the cyclist the second velocity must be from the North so that together they produce the 32 m./sec. velocity having a Northerly component at 20 degrees.
Format you need is a triangle of velocities, with the Westerly (one side) and hypotenuse N-W velocities specified as in the question. Find the length of the other side of the triangle.

Relative velocity?
Car A is traveling at 75 km/h while car B is at 57 km/h.
What is the relative velocity of car A to car B if they are headed towards each other?
The answer is not -93, 93, -18, or 18. Does anyone have any other suggestions? Thanks
Im sorry, the answer needs to remain in km/h. And scratch the -93, +93, I meant -132 and +132
Ive found the answer, you add them together and make them positive.
Answer: Va = 75km/h *1h/3600s *1000m/1km = 20.8333 m/s
Vb = 57km/h * 1h/3600s *1000m/1km 0 15.8333 m/s
Vb-Va=Vab
15.8333 - 20.8333 = -5 m/s
I guess you should first calculate them in SI .

How do I calculate relative velocity???? Please help me with my questions??? MidTerms coming up?
Question:
A boat heading due north crosses a 2km wide river with a velocity of 10km/h relative to the water. The river has a velocity of 5kn due East.
a.) Determine the velocity of the boat with respect to an observer on the bank.
b.) How long does it take the boat to cross the river?
c.) How far downstream (east) is the boat when it has crossed the river?
Answer: let v1(vector) be the velocity of the boat relative to the water, v2 be the velocity of the water to the bank, v be the velocity of the boat to the bank
a)You must know this formula v(vector)=v1(vector)+v2(vector)
Hence v^2(square v)=v1^2+v2^2+2*v1*v2*cosb
(b is the angular between v1(vector) and v2(vector))
Here b=90 so cosb=0 so v=squareroot(v1^2+v2^2)
b) t=2/10 (h)
c) The distance we have to calculate is caused by the velocity of the water
Hence d=v2*t

What is the relative velocity of a man in a boat with respect to the river and the earth?
A river flows due south with a speed of 2.00m/s . A man steers a motorboat across the river; his velocity relative to the water is 4.20m/s due east. The river is 800m wide.
What is the magnitude of his velocity relative to the earth? What is the direction of his velocity relative to the earth? How much time is required for the man to cross the river?
Answer: With respect to the Earth, there are two components of velocity
-2.00 m/s (South)
and 4.2 m/s (East)
the magnitude is
sqrt(4+4.2^2)
The direction is
ATAN(2/4.2) South of East
To cross to the opposite bank will be
800=4.2*t
t=800/4.2

Could someone help me set up this relative velocity question?
Heres the question:
Mark rode his personal watercraft at a constant speed of 30 kmh-1 directly across a river running at 5 kmh-1 downstream.
What is Mark’s velocity relative to the bank?
I know the answer, however I do not know how to solve it, let alone draw a vector for it. If anybody could explain or help me set this up, it would be greatly appreciated!

RV-sized asteroid will buzz the Earth on Monday | Bad Astronomy
A rock about 10 meters in size will fly past the Earth Monday at 13:30 UTC (09:30 Eastern US time). It’ll be a particularly close shave — passing just 12,400 km (7430 miles) from Earth’s surface; a bit less than the diameter of the Earth itself — but it’ll miss for sure. We’re in no danger from the asteroid, named 2011 MD, since there’s essentially zero chance it will hit us. Even if it did, it ...

relative velocity?
how to do well in relative velocity? i dont even understand the basic concept.
Answer: We will use nascar as an example since i love nascar. Imagine you are sitting at the track watching two cars race. Each car has a real velocity (car1=150 m.p.h. and car2=200 m.p.h.). Now if you were to jump in car1 and ride around the track at the same speed car2 would now have a relative velocity of 50 m.p.h. Before when you were sitting at the track you could see how fast each car was traveling but when you are in car1 traveling at 150 m.p.h. car2 will appear to be traveling at only 50 m.p.h. (200-150). If the positions were reversed and you were in car2, car1 would appear to be traveling at -50 m.p.h. (falling behind your car) even though you know he is going 150 m.p.h. Relative velocity just depends on where you are measuring the speed.
