A student rolls a ball down the ramp shown in the picture below. The ramp is supported by four stacked books. The student removes two books from the stack supporting the ramp and rolls the ball down the ramp again. Which of the following statements best describes how the ball’s motion is different after the books are removed?

• The ball accelerates more quickly down the ramp.
• The ball has a higher speed at the top of the ramp.
• The ball takes more time to reach the bottom of the ramp.
• The ball has a higher average speed when it rolls off the ramp

The diagram below shows the top view of two carts with different masses on a frictionless surface. The carts are pushed from rest, and they reach the finish line at the same time. Which of the following statements describes and explains the forces applied to the carts?

• Equal force is required to push the carts because they move on a frictionless surface.
• Equal force is required to push the carts because they reach the finish line at the same time
• A greater force is applied to cart Y because it accelerates at the same rate as cart Z but has less mass.
• A greater force is applied to cart Z because it accelerates at the same rate as cart Y but has more mass.
