A 2.40-kg cylindrical rod of length 2.00 m is suspended from a horizontal bar so it is free to swing about that end. A solid sphere of mass 0.25 kg is thrown horizontally with a speed v, = 13.5 m/s to hit the rod at the point A one-fifth of the way up from the bottom of the rod. The sphere bounces back horizontally with a speed v, = 9.50 m/s, while the rod swings to the right through an angle 0 before swinging back toward its original position. What is the angular speed of the rod immediately after the collision? rad/s (a) (b)
