Determine
(a) The power required to overcome the aerodynamic drag.
(b) Rolling resistance for a bicyclist traveling at a velocity of 21 km/h, if cd = 0.8, A = 1.5 m2, ρ = 1.2 kg/m3, f = 0.01 and m = 100 kg. Also determine.
(c) The metabolic energetic efficiency (work output/energy input) for the bicyclist if the rate at which calories are burned is measured at 650 Calories/h.
