Katie sits on the ground and rests her hands on a bowling ball in front of her. She uses all her force to push the bowling ball away from her body. Next, Katie rests her hands on a soccer ball situated in front of her at the same location. She uses all her force to push the soccer ball away from her body. How do the movements of the two balls contrast?

Ⓐ The soccer ball accelerates faster and moves a greater distance because more force is acting on it.

Ⓑ The soccer ball accelerates faster and moves a greater distance because it has less mass.

Ⓓ The bowling ball accelerates slower and moves a shorter distance because less force is acting on it.

Ⓑ The soccer ball accelerates faster and moves a greater distance because it has less mass.
