Angelina wants to observe what will happen when two rocks with different masses are pushed down a slide. Angelina puts the two rocks at the top of the slide and pushes each rock with an equal force. Below the slide, Angelina's friend Mary stands to catch the sliding rocks. Based on Newton's law of force and acceleration, what happens to the rocks as they are traveling down the slide?
A) The acceleration of each rock is equal to zero.
B) The rock with the smaller mass has less acceleration than the larger rock.
C) The two rocks have the same acceleration.
D) The rock with the larger mass has less acceleration than the smaller rock.
