A box with mass 1.68 kg is being pulled across a rough surface with a coefficient of kinetic friction k = 0.329. The pulling force has a magnitude of 14.4 N and is directed at an angle 24.8 degrees above horizontal. If the box is dragged a distance of 14.7 m, what is the magnitude of total energy lost to friction? (Report your answer as a positive number, and be sure to account for the upward component of the pulling force.) m F Image size: S ML A box with mass 1.68 kg is being pulled across a rough surface with a coefficient of kinetic friction k = 0.329.
