On land, coal is transported primarily by train. A typical large coal train may
be about 1.5 km long and may consist of 120 cars, each holding 110 tonnes of coal. As each tonne of coal has an equivalent energy content (in terms of the stored chemical energy it contains), a moving coal train represents a flow of (chemical) energy or a power. For acoal train traveling at 100 km/h, calculate the equivalent power in watts.
