1 Chapter 7 Linear Momentum 4. A 30.00 kg mass falls from a height of 4.000 m. The momentum of the mass just before it hits the ground is: A. 144.2 kg m/s. B. 187.8 kg m/s. C. 320.0 kg m/s. D. 442.4 kg m/s. E. 502.1 kg m/s. 5. A 3.000 kg ball is pitched with a kinetic energy of 20.00 Joules. Then the momentum of the ball is: A. 7.500 kg m/s. B. 8.350 kg m/s. C. 9.450 kg m/s. D. 10.95 kg m/s. E. 12.50 kg m/s. 6. If the momentum of a ball is doubled, then the kinetic energy is: A. 0.5 times larger. B. 2 times larger. C. 3 times larger. D. 4 times larger. E. 5 times larger. 8. A 4.00 kg ball is traveling at 5.00 m/s and strikes a wall. The 4.00 kg ball bounces off the wall with a velocity of 4.0 m/s. The magnitude of the change in momentum of the ball is: A. 8.0 kg m/s. B. 13 kg m/s. C. 26 kg m/s. D. 30 kg m/s. E. 36 kg m/s.

2 10. A 4.00 kg ball is traveling at 3.00 m/s and strikes a wall. The 4.00 kg ball bounces off the wall with a velocity of 4.0 m/s. If the contact with the wall by the ball lasts for 0.10 seconds, then the average force on the ball is: A. 230 N. B. 280 N. C. 320 N. D. 360 N. E. 400 N. 11. A 5.00 kg ball is moving at 4.0 m/s to the right and a 6.00 kg ball is moving at 3.00 m/s to the left. The total momentum of the system is: A. 2.0 kg m/s to the right. B.
