This is a KIN 3112 (Biomechanics)

A soccer player kicks a ball with a mass of m = 425g toward the goalkeeper. Directly before hitting the goalkeeper's hands, the ball travels horizontally at a velocity of vi = 58 mph. The stopping time until the goalie brings the ball to a full rest is t = 4.5 ms. a) What is the linear momentum of the ball just before contact? (2 pts.) b) What is the average force exerted by the goalie's hands to stop the ball? (2 pts.) c) How much mechanical work is required to catch the ball? (2 pts.)
