A 71.0 kg diver steps off a diving board and drops straight down into the water. The water provides an upward average net force 1110 N. If the diver comes to rest 4.1 m below the water's surface, what is the total distance between the diving board and the diver's stopping point underwater?

Question

bobpursley · Answer

resisting net force*distance=PE at top of board. 1110*4.1=71*g*h solve for h. height h is the total distance from the board to the stopping point.

Why. · Answer

This is simply incorrect.

Dave · Answer

I agree, bob is using the PE equation (deltaPE=mgh)
