An object moves from point A to point B under the influence of only two forces. Between points A and B, one force is conservative and does + 150 J of work while the other force is non- conservative and does – 100 J of work. Which one of the following statements describes the situation correctly? A. the kinetic energy of the object increases and its mechanical energy decreases. B. both the kinetic energy and the mechanical energy of the object increase. C. the kinetic energy of the object decreases and its mechanical energy increases. D. both the kinetic energy and mechanical energy of the object decrease.

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. If the work done by frictional forces doesnt change, would the shoppers applied force be larger, smaller, or the same? What about the work done on the cart by the shopper?
