A lead ball is dropped into a lake from a diving board 6.20 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 4.80 s after it is released. How deep is the lake?
A person stands on a diving board and tosses a stone into a swimming pool. The stone is thrown from a height of 2.9 m above the water surface with a velocity of 2.8 m/s at an angle of 38° above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the stone enters the water, it moves in a straight line in the direction of the velocity it had when. it struck the water. If the pool is 4 m deep, how much time elapses between when the stone is thrown and when it strikes the bottom of the pool? ttotal = S
