A shopper in a supermarket pushes a cart with a force of 35 Newton directed at an angle of 25 degree below the horizontal. The force is just sufficient to overcome various frictional forces, thus the cart moves at fix speed.

(a) Obtain the work done by the shopper as she moves down a 48 meter length aisle.

J

(b) Calculate what is the net work done on the cart?
