A lead ball is dropped into a lake from a diving board 5 m above the water. After entering the water, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the water. The ball reaches the bottom 3 seconds after it is released. Use g= 9.8 m/sec^2.

a) Draw a motion diagram for the problem.

b) How deep is the lake?
