A person pushes a 16.0 kg shopping cart at a constant velocity for a distance of 18.0 m. She pushes in a direction 23.0° below the horizontal. A 52.0 N frictional force opposes the motion of the cart.

A) What is the magnitude of the force that the shopper exerts? (answer in N)

B) Determine the work done by the pushing force. (answer in J)

C) Determine the work done by the frictional force. (answer in J)

D) Determine the work done by the gravitational force. (answer in J)
