A coin rests 15.0 cm from the center of a turntable. The coefficient of static friction between the coin and turntable surface is 0.390. The turntable starts from rest at t = 0 and rotates with a constant angular acceleration of 0.630 rad/s2. (a) After 3.00 s, what is the angular velocity of the turntable?

  • physics - ,

    You are given angular velocity initial, angular acceleration, and time.
    use wf=wi+at
    wf=0+(0.630rad/s)*(3s)
