You are designing a ski jump ramp for the next winter olympics. you need to calculate the vertical height (h) from the starting gate to the bottom of the ramp. the skiers push off hard with their ski poles at the start, just above the starting gate, so they typically have a speed of 2.0 m/s as they reach the gate. for safety, the skiers should have a speed of no more than 30.0 m/s when they reach the bottom of the ramp. you determine that for a 85.0 kg skier with good form, friction and air resistance will do total work of magnitude 4000 j on him during his run down the slope. what is the maximum height (h) for which the maximum safe speed will not be exceeded?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
