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?
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.
$\displaystyle \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.
