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?

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