Q. A spotlight on a boat is y = 2.1 m above the water, and the light strikes the water at a point that is x = 7.4 m horizontally displaced from the spotlight. The depth of the water is 4.0 m. Determine the distance d, which locates the point where the light strikes the bottom.
Q. A 65.0 kg person throws a 0.0450 kg snowball forward with a ground speed of 30.0 m/s. A second person, with a mass of 60.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard friction between the skate and the ice.
