Answer 1

For Question 1: To increase the net force on the cart, the correct choice would be "Applying a braking force by dragging your foot." This is because applying a braking force would create an unbalanced force on the cart, leading to a change in its motion.

For Question 2: When the problem states that a cart is moving along a road at a constant velocity, it means that "All the forces acting on the cart equal zero net force." This indicates that the forces are balanced, resulting in no change in the cart's velocity.
