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 5 N , how much force does the ball exert on the player’s foot and in what direction?(1 point)
Responses

5 N backward
5 N backward

5 N forward
5 N forward

100 kg forward
100 kg forward

10 kg/N backward

Answer 1

5 N backward.

By Newton’s third law, the ball exerts an equal and opposite force on the foot, so if the player applies 5 N forward, the ball applies 5 N backward.
