As an object moves from point A to point B only two forces act on it: one force is nonconservative and does +40 J of work, the other force is conservative and does - 60 J of work. Between A and B, a. The potential energy of the object increases, mechanical energy decreases. b. The potential energy of the object decreases, mechanical energy decreases. c. The potential energy of the object decreases, mechanical energy increases. d. The potential energy of the object increases, mechanical energy increases.

a shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25 below the horizontal. The force is just sufficient to overcome various frictional forces, so the cart moves at constant speed, (a) Find the work done by the shopper as she moves down a 50.0-m length aisle, (b) What is the net work done on the cart? Why? (c) The shopper goes down the next aisle, pushing horizontally and maintaining the same speed as before.
