Question

Problem 4: At a local swimming pool, the diving board is elevated h = 9.5 m above the pool's surface and overhangs the pool edge by L = 2 m. A diver runs horizontally along the diving board with a speed of vo = 4.8 m/s and then falls into the pool. Neglect air resistance. Use a coordinate system with the horizontal x-axis pointing in the direction of the diver's initial motion, and the vertical y-axis pointing up. Part (a) Enter an expression for the time Iw it takes the diver to fall off the end of the diving board to the pool's surface in terms of vo, h, L, and g. Expression: W= Select from the variables below to write your expression. Note that all variables may not be required. a., B, 0, a, b, c, d, g, h, i, j, k, L, m, n, P,r, t, T, V, Part (b) Calculate this time, tw in seconds. Numeric : Anumeric value is expected and not an expression. Part (c) Determine the horizontal distance, dw in meters, from the edge of the pool to where the diver enters the water. Numeric : Anumeric value is expected and not an expression. d.
