(20%) Problem 3: A box with a mass of 7.93 kg is sliding along a horizontal surface at constant velocity. It is pulled by a horizontal force, and the coefficient of kinetic friction between the box and the surface is 0.241. 33% Part (a) What is the work done, in joules, by the pulling force as the box moves a distance of 0.647 m?
