The head of the golf club is in contact with a 46g is 0.5ms and results in the ball to flies off at 70 m/s. Find the impulse and average force acting on the ball during the impact.

A professional boxer hits his opponent with a 1075 N horizontal blow that lasts 0.190 s. The opponent's total body mass is 105 kg and the blow strikes him near his center of mass and 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. m/s

irai, a 50 kg figure skater, lands on the ice her feet after landing the triple axel and immediately jumps up again to perform a double toe-loop. The instant before her skates first touch the ice after the triple axel, her vertical velocity is 3 m/s downward. Her velocity is 2 m/s upward when her skates leave the ice for the second jump, 0.8 s later. (a) What is the vertical impulse exerted on Mirai during the 0.8 s she is in contact with the ice between the two jumps? (b) What is the average net vertical force exerted on Mirai during this 0.8 s? (c) What is the average reaction force exerted upward by the ice on Mirai during the 0.8 s?

A sliotar of mass 115 g moves horizontally with an initial velocity of 38.0 m/s as it approaches a hurley. The hurley applies an average force to the sliotar so that it departs from the hurley travelling at 58.0 m/s in the opposite direction. The duration of the impact between the sliotar and hurley is 12.1 ms. Find (a) the impulse imparted to the sliotar by the hurley, and (b) the average force exerted on the sliotar by the hurley.
