For Question 1: The choice that would increase the net force on the cart is:
**Applying a braking force by dragging your foot.**
This applies a force in the opposite direction to the motion of the cart, thus increasing the net force acting on it.
For Question 2: The correct response is:
**All the forces acting on the cart equal zero net force.**
This means that the forces are balanced, leading to a constant velocity as per Newton's first law of motion.
**Applying a braking force by dragging your foot.**
