time is 0 with an initial ccw angular velocity of w0 = 0.5 rad/sec.
The bar shown is rotating around a fixed point O with an angular
acceleration a=k/w^4 with the constant k = 150 sec^-6 (units are
rad/sec^2)
once the bar reaches an angular velocity of w=5 rad/sec
counterclock wise, the angular displacement of the bar from its

1) An outfielder throws a ball that has an initial angular speed of 40.0 rad/s. After 0.95 s, the ball is caught by an infielder. Its angular speed is then 30.0 rad/s. Assume that air resistance gave the ball a constant angular acceleration. How many revolutions did the ball make before being caught? B) How long did it take for the ball to complete two revolutions?
