Physics

A professional boxer hits his opponent with a 1345-N horizontalblow that lasts for 0.122 s.

a) Calculate the impulse (in kg · m/s) imparted by thisblow.

b) What is the opponent's final velocity (in m/s), if his massis 113 kg and he is motionless in midair when struck near hiscenter of mass?

c) Calculate the recoil velocity (in m/s) of the opponent's 11.4kg head if hit in this manner, assuming the head does not initiallytransfer significant momentum to the boxer's body.
