The diagram shows two boulders that are rolling down a mountain slope. The mass of one boulder is 1,000 kilograms, and the mass of the other boulder is 50 kilograms. If both of the boulders are moving at the same speed, which of the following statements is true when both reach point A before touching the ground?

• The boulders have the same kinetic energy.

• The 1,000-kg boulder has more kinetic energy than the 50-kg boulder.

• Neither boulder has any kinetic energy.

• The 50-kg boulder has more kinetic energy than the 1,000-kg boulder.
