Question

In springboard diving, the diver strides out to the end of the board, takes a jump onto its end, and uses the resultant spring-like nature of the board to help propel him into the air. Assume that the diver's motion is essentially vertical. He leaves the board, which is 3.2 m above the water, with a speed of 6 m/s. (a) How long is the diver in the air, from the moment he leaves the board until he reaches the water? (b) What is the speed of the diver when he reaches the water?
