5. amy and josh are coasting on their bicycles down a 10° slope at 15 m/s through still air. the mass of amy and her bicycle is 60 kg. the mass of josh and his bicycle is 90 kg. the cross-sectional area of amy and her bicycle is 0.45, while the cross-sectional area of josh and his bicycle is 0.60. the drag coefficient for both cyclists is 0.70. other than gravity and air resistance, the external forces acting on the two bicycle and rider systems are the same. which cyclist is more affected by air resistance? the answer is amy but what is the math invovled, show work and !

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
