What are the velocities afher the collision? a) Both are zero, b) The magn c) One of the particles continues with the same d) One of the particles continues with the same velocity, and the other reverses itudes of the velocities are the same, but the directions are reversed velocity, and the other comes to rest direction at twice the speed e) More information is required to determine the final velocities. 1.7: Bob and Lily are riding on a merry-go-round. Bob rides on a horse toward the outer edge of a circular platform and Lily rides on a horse toward the center of the circular platform. When the merry-go-round is rotating at a constant angular speed o, Bob's speed vis a) exactly half as much as Lily's. b) larger than Lily's. c) smaller than Lily's d) the same as Lily's. e) exactly twice as much as Lily's. 1.8: Compare the weight of a mountain climber when she is at the bottom of a mountain with her weight when she is at the top of the mountain. In which case is her weight larger? a) She weighs more at the bottom. b) She weighs more at the top. c) Both are the same. d) She weighs twice as much at the top e) She weighs four times as much at the top. 1.9: Two satellites having equal masses are in circular orbits around Earth. Satellite A has a smaller orbital radius than satellite B. Which statement is true? a) Satellite A has more kinetic energy, less potential energy, and less mechanical energy (kinetic energy plus potential energy) than satellite B. b) Satellite A has less kinetic energy, less potential energy, and less mechanical energy than satellite B Satellite A has more kinetic energy, more potential energy, and less mechanical energy than satellite B. c) d) Satellite A and satellite B have the same amount of mechanical energy e) Satellite A and satellite B have the same amount of kinetic energy and no potential energy because they are in motion. 1.10: Two wooden boxes of equal mass but different density are held beneath the surface of a large container of water. Box A has smaller average density than box B. When the boxes are released, they accelerate upward to the surface. Which box has the greater acceleration? a) Box A b) Box B

Explanation / Answer

1.6) (b) the magnitude of the velocities are the same, but the directions are reversed.

As the masses are equal and so are the velocities, just the direction reverses.
