.22 A 100,000 kg engine is moving up a slope of gradient 5° at a speed 100 m/s. The coefficient of friction between the engine and the rails is 0,1. If the engine has an efficiency of 4 % for converting that into work, find the amount of coal, the engine has to burn up in one hour (Burning of 1 kg of coal yields 50,000 joules).
