A 75.0 kg diver steps off a diving board and drops straight down into the water. The water provides an upward average net force 1060 N. If the diver comes to rest 4.9 m below the water's surface, what is the total distance between the diving board and the diver's stopping point underwater?
Work done opposing the upward buoyant force equals P.E loss from the diving board to the stopping point
1060N*4.9 m = M g X
M g = 735 N
X is the distance you want.
X = (1060/735)4.9 = 7.1 meters
The height of the diver is being neglected here.
