A pitcher throws a curveball that reaches the catcher in 0.67 s. The ball curves because it is spinning at an average angular velocity of 340 rev/min (assumed constant) on its way to the catcher's mitt. What is the angular displacement of the baseball (in radians) as it travels from the pitcher to the catcher?

Steve,
340rev/min * 2π rad/rev * 1 min/60sec * 0.67 sec = 23.9 rad
