To increase the net force on the cart, you would need to apply a force that results in a change in the cart's state of motion (which refers to acceleration). Among the choices, the only action that directly results in a change to the net force is:
**Applying a braking force by dragging your foot.**
This action applies a force in the opposite direction of the cart's motion, increasing the net force acting on the cart (since the net force is the vector sum of all forces acting on it). The other options (moving on a smooth surface, decreasing the mass, or polishing the floor) would not directly lead to an increase in net force.
