Question

alice kicks a 0.25 kg soccer ball with 0.5 n of force. what force does the ball exert on alices foot as she kicks it?
n

Explanation:

Step1: Recall Newton's Third Law

For every action force, there is an equal and opposite reaction force.

Step2: Apply to the problem

The force Alice exerts on the ball ($0.5\ \text{N}$) is the action force, so the reaction force (ball on foot) is equal in magnitude.

Answer:

$0.5$
