Given Data: The force applied by a boxer is, F=1200 N The time required for the horizontal blow is, t=0.145 s Part (a): The expression for the impulse is given as, J=F×t...............(1) Here, F is the force and t is the time. To calculate the impulse imparted by the blow, substitute the values in equation (1) J=1200 N×0.145 sJ=174 kg·m/s Therefore, the impulse imparted by the blow is 174 kg·m/s. Part (b): To calculate the opponent's final speed, use Newton's first equation of motion, v=u+at ∴F=mav=0 m/s+1200 N105 kg×0.145 sv=1.66 m/s Therefore, the opponent's final speed is 1.66 m/s. Part (c): To calculate the final speed of his head, use Newton's first equation of motion, v=u+at ∴F=ma v=0 m/s+1200 N5.48 kg×0.145 s v=31.75 m/s Therefore, the final speed of his head is 31.75 m/s.
