18 . Diving Board Problem Suppose that you spring into the air from the 3-meter diving board. You hit the water, 3 meters below the board, at 1.6 seconds from the time you sprang. a. What was your initial upward velocity, r? b. When do you pass the board on your way back down? c. How high above the board did you go? d. If you spring from the 1-meter board with the same initial up- ward velocity as in part (a) when will you hit the water? e. If another diver steps off the 10-meter platform (initial velocity sr = 0 ) at the same time as you spring from the 3-meter board, as in part (a), who reaches the water sooner? How much sooner?
