Answer to Question #39258 in Molecular Physics | Thermodynamics for None

Question

A force of 315 N is applied horizontally to a crate in order to displace the crate 37.5 m across a level floor at a constant velocity. As a result of this work, the crate's internal energy is increased by an amount equal to 21 percent of the crate's initial internal energy. Calculate the initial internal energy of the crate.
