Johnny used his super muscle power to pull a box initially at rest, up an inclined plane. The inclined plane makes an angle of 35o with the horizontal and Johnny applied a force of 250 N parallel to the incline. The mass of the box is 25.0 kg and the coefficient of kinetic friction between the box and the surface is 0.45. The box moves up the incline a distance of 5.0 m. Find the magnitude of the work done by the weight of the box . g = 9.81 m/s2
