A bicyclist can coast down a 8.18 degree hill at a constant speed of 5.55 km/h. If the force of air resistance is proportional to the speed v so that Fair = c v, calculate the average force (in N) that must be applied in order to descend the hill at 19.3 km/h. The mass of the cyclist plus bicycle is 78.6 kg.
