QUIZ # 1 SET A

1. A roller-coaster car moves 200 ft horizontally and then rises 135 ft at an angle of 30.0° above the horizontal. It next travels 135 ft at an angle of 40.0° downward. What is its displacement from its starting point?

2. A man drops a rock on a deep well. The man hears the sound of the water splash after 2.4 s. The speed of sound in air is 336 m/s. How far from the surface of the water is the top of the well?

3. Kuroko Tetsuya just developed his invisible high-angle shot. Let us assume that he can shoot/push the ball with an initial speed of 12 m/s with an angle of 80° from the horizontal axis; and that the ring is 1 m above the ball’s point of release. What is the maximum distance from the ring that he can make the shot?
