A box with mass 1.60 kg is being pulled across a rough surface at a constant speed with a coefficient of kinetic friction µ_k = 0.310. The pulling force has a magnitude of 12.1 N and is directed at an angle 39.7 degrees above horizontal. If the box is dragged a distance of 11.2 m, what is the total energy lost to friction? (Hint: be sure to account for the upward component of the pulling force, and note that the energy lost to friction is being compensated for by the work added by the pulling force)
