A lead ball is dropped into a lake from a diving board 5.60 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 4.70s after it is released. Part A How deep is the lake? Express your answer with the appropriate units.

Set the controls as follows. x0 =  6  cm k = 80 N/m m = 4 kg Now hit start and observe the motion of the block and the plots on the graphs for position, velocity, and acceleration. Which of the following statements accurately describes your observation? (Select all that apply.) The maximum displacement was 6 cm. The maximum displacement was 0 cm. The speed of the block remained constant. The acceleration of the block remained constant. The frequency of the block remained constant. The period of the block remained constant.     Set the controls as follows. x0 =  6  cm k = 80 N/m m = 1 kg Now hit start and observe the motion of the block and the plots on the graph for position, velocity, and acceleration.
