A golf ball with mass 5.0x10^-2 kg is struck with a club. The force on the ball varies from zero when contact is made up to some maximum value and then back to zero when the ball leaves the club, as in the graph of force vs time. Assume that the ball leaves the club face with a velocity of 44m/s. (20pts) a. Find the magnitude of the impulse due to collision. b. Estimate the duration of the collision and the average force acting on the ball
