Calculate the work done by the shopper

Reference no: EM13661057

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, therefore the cart moves at a stable speed.

(a) Calculate the work done by the shopper as she moves down a 50.0 meter length aisle.

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