A diver springs upward with an initial speed of 19 ms from, Ask an Expert

Academics

A diver springs upward with an initial speed of 1.9 m/s from a 2.5 m board.

(a) Find the velocity with which he strikes the water. (Hint: When the diver reaches the water, his displacement is y = -2.5 m (measured from the board), assuming that the downward direction is chosen as the negative direction.)What is the highest point he reaches above the water?
