A pitcher throws a curveball that reaches the catcher in 0.55 s. The ball curves because it is spinning at an average angular velocity of 335 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?
Is my answer correct?
disp = angular vel x time
disp = (335x360x0.1745/60)x 0.55
disp = 19.29 radians
0.55 s * 335/60 (rev/s) * 2 pi (rad/rev) => same answer. Looks good to me
Thanks!
