Question
A person pushes a 16.0-kg shopping cart at a constant velocity for a distance of 22.0 m. She pushes it in the direction 30.0° below the
horizontal. A 48.0-N frictional force opposes the motion of the cart. (a) Draw the free-body diagram showing the forces that act on the
cart. (b) What is the magnitude of the force that the shopper exerts? Determine the work done by (c) the pushing force, (d) the
frictional force, and (e) the gravitational force.
Step 1
Incorrect.
(a) Draw the free-body diagram showing the forces that act on the cart.
Use the checkboxes to select the correct vectors as instructed above. Move the vectors
to the correct starting points and orient them in the correct direction as instructed.
