At the local swimming pool, the diving board is elevated h = 8.5 m above the pool surface and overhangs the pool edge by l = 2 m. a diver runs horizontally along the diving board with a speed of v0 = 3.7 m/s and then falls into the pool. neglect air resistance. use a cartesian coordinate system with its origin at the position of the diver just before falling. let the direction that the diver falls be the negative y direction.
a) express the time (tw) it takes the diver to move off the end of the diving board to the pool surface in terms of v0, h, l, and g.
b) calculate the time, tw, in seconds, it takes the diver to move off the end of the diving board to the pool surface.
c) determine the horizontal distance, dw, in meters, from the edge of the pool to where the diver enters the water.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
