A conveyer belt running at a constant speed at an incline of 35.0 degrees above the horizontal. Friction pulls a 9.0 kg box up with the movingsurface of the conveyer belt. The box is moving at a constant speed of 2.95 cm/s. During this time, the box moves 6.35 m along the inclinedsurface.a) How much work does friction do on the box?b) How much work does the force of gravity do on the box?c) How much work does the normal force do on the box?

Box moving at a constant velocity implies that there in no external force in the system, from 1st…
