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.
