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.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
