# Thread: Angular Velocity

1. ## Angular Velocity

Can someone solve this question for me???

1) Through how many degrees does a wheel rotate in 10m/s if its angular velocity is 8 rad/s?

The question doesn't really make sense...

Are you sure that's the question? Did you mean 10m/s and not 10s?

3. Yeah 10m/s......as in 10 meters per second. thanks

I'm afraid the question still doesn't make sense.

It is not clear what you are being asked to find.

5. ## Maybe this will help

That question is part b of a question the Part a is listed below. I thought the two were unrelated but maybe not. Hopefully you can help

a) State the amplitude (A) the period (T) and the frequency (F) for the periodic function - 120sin (100 pi t)V.

6. It would seem that part a) and part b) ARE unrelated.

You are given an angular velocity, measured in radians per second and asked to find the angle through which a wheel has rotated.

To find the angle through which a wheel rotates you must multiply the angular velocity by a time.

i.e.

$\text{Angle} = \text{Angular Velocity} \times \text{Time}$

However, you have not been given the time that you need. All you have been given is a normal speed, which is irrelevant for what you are trying to find.
