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.
