An Athlete pulls a 20 kilograms crate along Lane A of the storage house. Lane A is a 15m aisle. Using the yellow rope, he exerted an 80N force 15 degrees above the horizontal. Q:-How much work is done by the athlete?-If the crate moves at constant velocity and the 80N force is enough to overcome friction , what is the net work done by all the forces acting on the box?
