Q1. A tennis ball of mass 57 g travels with velocity < 48, 0, 0 > m/s toward a wall. After bouncing off the wall, the tennis ball is observed to be travelling with velocity < -42, 0, 0 > m/s.
What is the change in the momentum of tennis ball?
What is the magnitude of the change of momentum of tennis ball?
What is the change in the magnitude of tennis ball's momentum?
Q2. A large Lucite cube (n = 1.49) has a small air bubble (a defect in the casting process) below one surface. While a penny (diameter 1.6 cm) is placed directly over the bubble on the outside of the cube, the bubble cannot be seen by looking down into the cube at any angle. However, when a dime (diameter 1.624 cm) is placed straight over it, bubble can be seen by looking down into the cube.What are upper and lower bounds of the range of the possible depths of the air bubble beneath surface?
