A 59.0 kg diver steps off a diving board and drops straight down into the water. The water provides an upward average net force 1050 N. If the diver comes to rest 4.5 m below the water's surface, what is the total distance between the diving board and the diver's stopping point underwater?

let d equal total distance

59.0 kg * g * d = 1050 N * 4.5 m

d = 1050 * 4.5 m / (59.0 * 9.8)
