A pickup truck is moving at 25 m/s when suddenly the brakes are applied and the truck comes to a stop in 4.7 s. A tool box of mass m rests on the bed of the truck 2.5 m from the cab. If the coefficient of kinetic friction between the tool box and the bed of the truck is 0.28, how much time elapses before the tool box strikes the cab?
