A person pushes a 16.0 kg shopping cart at a constant velocity for a distance of 22.0 m. She pushes in a direction 26.0° below the horizontal. A 60.0 N frictional force opposes the motion of the cart.
(a) What is the magnitude of the force that the shopper exerts?
N
(b) Determine the work done by the pushing force.
J
(c) Determine the work done by the frictional force.
(d) Determine the work done by the gravitational force.
