Determination of maximum height reached by the diver using equation of motion.

A diver springs upward with an initial speed of 1.8 m/s from a 3.0-m board,

(a) Find out the velocity with which he strikes the water. [Hint: When the diver reaches the water his displacement is y= -3.0m (measured from the board), assume that the downward direction is chosen as the negative direction.].

(b) What is the highest point he reaches above the water?
