A man pushes a 16.0 kilogram shopping cart at a constant velocity for a distance of 24.0 meter. She pushes in a direction 25.0 degree below the horizontal. A 52.0 N frictional force opposes the motion of the cart.
(a) Find the magnitude of the force that the shopper exerts?
N
(b) Find the work done by the pushing force.
J
(c) Evaluate the work done by the frictional force.
J
(d) Find the work done by the gravitational force.
