5. A nurse (Fig. 6-4) pushes a patient on a cart 20.7 m down a hall with a constant speed of 0.88 m/s, doing 2000 J of work on the cart. If the cart is released it travels 0.48 m before coming to rest. Assuming the nurse exerts a horizontal force on the cart, determine the total weight of the cart plus patient. 2 Fig. 6-4
