Which statement below is the best example of Newton’s Second Law of Motion?

Question

1. A dog is pulling on his owner’s leash; the owner is pulling the leash with equal and opposite force
2. Two teams are tied in a tug of war.
3. A 0.43 kg football rests on the tee until the kicker kicks the football.
4. The acceleration of a 0.058kg tennis ball depends on the force of the racquet.

Answer 1

The best example of Newton’s Second Law of Motion from the provided statements is:

4. The acceleration of a 0.058 kg tennis ball depends on the force of the racquet.

This statement reflects Newton's Second Law, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma). In this case, the acceleration of the tennis ball (caused by the force from the racquet) is clearly being discussed.
