A grocery cart with a mass of 18 kg is pushed at constant speed along an aisle by a force F = 12 N. The applied force acts at a 20° angle to the horizontal. Find the work done by each of the forces on the cart if the aisle is 14 m long.
work done by the applied force
work done by the frictional force
work done by the normal force
work done by the gravitational force
Thankyou

The applied force is W = Fdcos(theta).
the normal force and gravitaional force do no work, because there is no motion on the y axis
