E6.) A ball experiences a change in momentum of 24 kg-m/s.a. What is the impulse acting on the ball?b. If the time of interaction is 0.15 s, what is the magnitude of the average force acting on the ball? Answer with the correct formula.

A professional boxer hits his opponent with a 1075 N horizontal blow that lasts 0.190 s. The opponent's total body mass is 105 kg and the blow strikes him near his center of mass and while he is motionless in midair. (a) Determine the impulse (in kg m/s) the boxer imparts to his opponent by this blow. kg m/s (b) Determine the opponent's final velocity (in m/s) after the blow. m/s (c) Calculate the recoil velocity (in m/s) of the opponent's 5.0 kg head if hit in this manner, assuming the head does not initially transfer significant momentum to the boxer's body. m/s
