Question: On land, coal is transported primarily by train. A typical large coal train may be about a 1.5 km long and consists of 120 cars each holding 110 tons of coal. As each ton of coal has an equivalent energy (bituminous coal with 27 MJ/kg) content, a moving coal train represents a flow of energy or a power. For such a coal train traveling at 100 km/h, calculate the equivalent power in Watts.
