Suppose that a cart is moving along a road at a constant velocity. Give two examples of ways to cause the cart to decelerate, explaining how the net force is affected.(2 points)

Answer 1

One example of a way to cause the cart to decelerate is by applying the brakes. When the brakes are applied, friction between the brake pads and the cart's wheels creates a force in the opposite direction of the cart's motion. This force acts as the net force and causes the cart to decelerate.

Another example is if an external force, such as a person pushing against the cart in the opposite direction of motion, is applied. This external force would also act as the net force and cause the cart to slow down.
