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.
