Two spheres A & B are projected off the edge of a 2.0 m high table with the same horizontal velocity. Sphere A has a mass of 10 g and sphere B has a mass of 5 g. X 5. Which ball will be in the air for the greater amount of time? A. Ball A B. Ball B. C. They will be in the air for the same amount of time. D. There is not enough information to decide 6. Ball A hits the floor at the spot marked X. Where will ball B hit the floor? A. at some point between the edge of the table and X. B. at the same distance from the table as X C. at some point past X D. There is not enough information to decide. 7. Which sphere has the greatest amount of momentum, just before it hits the ground? A Ball A B. Ball B C. They both have the same momentum D. Not enough information is provided. 8. A rifle recoils while firing a bullet. The speed of the rifle's recoil is small because the A force against the rifle is small compared to the force on the bullet B. speed is mainly concentrated in the bullet, C. rifle has lots of mass compared to the bullet. D. momentum of the rifle is unchanged. E none of these 9. In order to catch a ball, a baseball player moves his or her hand backward in the direction of the ball's motion. Doing this reduces the force of impact on the player's hand principally because it A. increases the impact time. B. decreases the impulse on the glove. C. decreases the change in momentum of the ball. D. all of the above E. none of the above 10. The momentum change of an object is equal to the A force acting on the object. B. velocity change of the object. C. impulse acting on the object D. mass of the object times the force acting on it.
