A nurse pushes a cart by exerting a force on the handle at a downward angle 35.0º below the horizontal. The loaded cart has a mass of 28.0 kg, and the force of friction is 60.0 N. (a) Draw a free-body diagram for the system of interest. (b) What force must the nurse exert to move at a constant velocity?

Step 1 of 3A nurse is pushing a cart by applying force at angle below horizontal. We have to first draw the free body diagram of the cart. Then we have to calculate the required force to applied by the nurse to move the cart at constant velocity. Part (a)
