Suppose that a cart is moving along a road at a constant velocity. Which choice below would increase the net force on the cart? (1 point)

Question

Applying a braking force by dragging your foot.

polish the floor that the cart wheels roll on.

Decrease the mass of the cart.

Have the cart move on a smooth surface such as ice.

Answer 1

The choice that would increase the net force on the cart is:

Applying a braking force by dragging your foot.

Applying a braking force would create a force in the opposite direction of the cart's motion, thereby increasing the net force acting on the cart. The other choices either reduce friction (which may decrease the net force opposing the motion) or do not directly introduce a force.
