A professional boxer hits his opponent with a 1250-N horizontal blow that lasts for 0.15 s. Calculate the impulse imparted by this blow, in kilogram meters per second. What is the opponent’s final speed, in meters per second, if his mass is 97.5 kg and he was at rest when struck near his center of mass? Now assume that just the opponent's head, with a mass of 4.54 kg, was hit in this manner. Calculate the final speed of his head, in meters per second, assuming the head does not initially transfer significant momentum to the boxer’s body.
