Question
Example 12.22
100,000 kg engine is moving up a slope
of gradient 5 at a peed 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)
