A cyclist is riding with a constant speed υ = 25 km/h over an inclined road with θ = 15°. The combined mass of the cyclist and bicycle is 85 kg. Neglecting aerodynamic drag, determine the number of calories (1 C = 4.184 kJ) burned by the cyclist in the course of 15 min if his muscle efficiency is 25%.
