A boy on a sled is pushed by his friend with a force of 15 N and he accelerates to 4.1 m/s2 after 5 m. Then the boy and his sister both sit on the sled and the friend again pushes with a force of 15 N and they accelerate to 2.1 m/s2 after 5 m. How does this support Newton’s 2nd Law of Motion? Answer in at least 3 sentences.
