A 350 kg crate is sliding down a rough incline with a constant speed υ = 7 m/s. Assuming that the angle of the incline is θ = 33° and that the only forces acting on the crate are gravity, friction, and the normal force between the crate and the incline, determine the work done by friction over every meter slid by the crate.
