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 v0 = 2.7 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. let the y-axis be directed vertically down. express the time t_w it takes the diver to move off the end of the diving board to the pool surface in terms of v_0, h, l, and g. calculate the time, t_w in seconds, it takes the diver to move off the end of the diving board to the pool surface. determine the horizontal distance, d_w in meters, from the edge of the pool to where the diver enters the water.

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
