1) How much force would you need to exert in order to stop a gun recoil if the recoil lasts for 0.2 s? The gun has a mass of 3.876 kg, which includes the 130 g mass of the bullet. The initial velocity of the bullet is measured to be 780 m/s ________N What is the speed of the gun right after the trigger is pulled?

2) A tennis ball has a velocity of 22 m/s and a mass of 58.4 g. After the ball hits a tennis racket, the velocity becomes twice that of the original speed and goes in the opposite direction. What is the force between the ball and the racket if the time that they interact is 0.08 s? Assume the force is constant.
