To achieve a greater change in motion (which can be interpreted as a greater change in velocity) for the first ball, Eli should push the first ball with a greater force compared to the second ball. According to Newton's second law of motion (F = ma), a greater force will result in a greater acceleration (and thus a greater change in velocity) for the same mass.
Therefore, the correct answer is:
**B Push the first ball with a greater force.**
Therefore, the correct answer is:
**B Push the first ball with a greater force.**
