A diver springs upward with an initial speed of 1.7 m/s from a 3.0-mboard.
a) Find the velocity with which he strikes thewater.
[Hint: When the diver reaches the water, his displacement isy = -3.0 m (measured from the board), assuming that thedownward direction is chosen as the negative direction.]
b) What is the highest point he reaches above the water?
