"What is the momentum of the bike? 2- What velocity must a 12 l kg car have in order to have the same momentum as a pickup truck which has a momentum of 5.63104 kgmfs east? Impulse: 3. Calculate the impulse on a tennis racket that hits a ball of mass 67 g travelling at 10 m/s so that it comes off the racket at a velocity of 50 m/s 4. A 0.40 kg soccer ball approaches a player horizontally with a velocity of 18 m/s to the north. The player strikes the ball and causes it to move in the opposite direction with a velocity of 22 m/s. What impulse was delivered to the ball by the player? Force and impulse 5. A 0.50 kg football is kicked with a velocity of 15 m/s to the right. A stationary receiver catches the ball and brings it to rest in 0.020 s. What is the force exerted on the ball by the receiver
