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 = 4.9 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.
Enter an expression for the time ty 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.
Calculate this time, ty in seconds.Determine the horizontal distance, dy in meters, from the edge of the pool to where the diver enters the water.

The figure shows a cord attached to a cart that can slide along a frictionless horizontal rail aligned along an x axis. The left end of the cord is pulled over a pulley, of
negligible mass and friction and at cord height h = 1.5 m, so the cart slides from x, = 5.0 m to x, = 2.0 m. During the move, the tension in the cord is a constant 29.0 N.
What is the change in the kinetic energy of the cart during the move?
