# A 0.145-kg ball is thrown horizontally at +19.0 ???? m/s and is hit back at -52.0 ????

A 0.145-kg ball is thrown horizontally at +19.0 ????̂ m/s and is hit back at -52.0 ????̂ m/s. If the contact time between bat and ball is 13.0 ms, calculate:

d. ) During the collision, the bat swings around by 120o . Calculate the magnitude of the torque applied to the bat, assuming conservation of energy
