You are designing a ski jump ramp for the next winter olympics. youneed to calculate the vertical height {h} from the starting gate to the bottom of the ramp. theskiers push off hard with their ski poles at the start, just abovethe starting gate, so they typically have a speed of 2.0{\rm{ m/s}} as they reach the gate. for safety, the skiersshould have a speed of no more than 30.0 {\rm{ m/s}} when they reach the bottom of the ramp. youdetermine that for a 86.0 kg skier with good form, friction and air resistance will dototal work of magnitude 4000 {\rm j} on him during his run down the slope. what is themaximum height {h} for which the maximum safe speed will not be exceeded?

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)
