A turntable rotates with a constant 2.25 rad/s2 angular acceleration. After 4.00 s it has rotated through an angle of 30.0 rad. What was the angular velocity of the wheel at the beginning of the 4.00-s interval?

Solution 13E Step 1: We can use the equation, = t + ½ t 2 0 z Where, - Angular displacement 0initial angular velocity - Angular acceleration z t - Time of rotation
