Rotational Motion Problem

  1. Oct 17, 2007 #1
    1. The problem statement, all variables and given/known data
    A rotating wheel requires 3.00s to rotate 37.0 revolutions. Its angular velocity at the end of the 3.00-s interval is 98.0 rads/s. What is the constant angular acceleration of the wheel?

    2. Relevant equations
    rotational kinematic equations??



    3. The attempt at a solution
    I do not know

    How would you do this problem if instead a ball rolled 37.0 meters in 3 seconds, and at the end of the 3 seconds it was moving at 98 m/s? Take those equations replace, x with theta, v with omega, a with alpha and you have the proper equation you'll need. The only difference between is that you're given the distance it traveled in rotations, you'll want it in radians.
