Decrease the mass of the cart. polish the floor that the cart wheels roll on. polish the floor that the cart wheels roll on. Question 2 When the problem states that a cart is moving along a road at a constant velocity. What does this mean about the forces acting on the cart?(1 point) Responses Constant velocity and force have no relationship. Constant velocity and force have no relationship. There are no forces acting on the cart. There are no forces acting on the cart. Constant velocity increases net force. Constant velocity increases net force. All the forces acting on the cart equal zero net force.

Answer 1

For Question 1, the correct choice that would increase the net force on the cart is:

Applying a braking force by dragging your foot.

This action applies a force in the opposite direction of the cart's motion, thereby increasing the net force acting on the cart.

For Question 2, the correct response is:

All the forces acting on the cart equal zero net force.

This means that since the cart is moving at a constant velocity, the forces acting on it are balanced, resulting in a net force of zero.
