Question

if a soccer ball’s mass is 5 kg and a player who weighs 50 kg kicks the soccer ball forward with a force of 7.5 n, how much force does the ball exert on the player’s foot and in what direction? (1 point) ○ 7.5 n forward ○ 10 kg/n backward ○ 7.5 n backward ○ 100 kg forward

Explanation:

Step1: Recall Newton's Third Law

Newton's Third Law states that for every action, there is an equal and opposite reaction. The action force here is the force the player exerts on the ball (7.5 N forward).

Step2: Determine the Reaction Force

By Newton's Third Law, the reaction force (the force the ball exerts on the player's foot) should be equal in magnitude (7.5 N) and opposite in direction (backward) to the action force.

Answer:

7.5 N backward
