Aprofessional boxer hits his opponent with a 1025-n horizontal blow that lasts 0.150 s. the opponent's total body mass is 116 kg and the blow strikes him near his center of mass and while he is motionless in midair.

determine the following.

(b) the opponent's final velocity after the blow

1.29 incorrect: your answer is incorrect. try to express the impulse in terms of the force and time the force acts and also in terms of the mass and speed. then see if you can combine these two expressions for the impulse to determine the final speed. m/s

(c) calculate the recoil velocity 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.

30.0 incorrect: your answer is incorrect. if the blow is to the head rather than the body, how does your solution to part (b) get modified? m/s
