A short box with a large flat base is made of iron. The box has mass mI = 890 kg and specific

heat cI = 450 J/kg◦C. The box is filled with water. The water has mass mW = 1220 kg and specific

heat cW = 4180 J/kg◦C. The box and water are initially at temperature T0 = 20◦C. The box is

chained to the back of a truck and is dragged down the road. The coefficient of kinetic friction

between the road and the box is μ = 0.70. The fraction of the mechanical energy dissipated by

friction that is added as heat to the box is f = 0.40.

Neglect any loss of heat to the surroundings and determine how far the truck travels before the

water reaches the boiling point.
