Question

According to Newton's third law of motion, if a rolling ball collides with a wall and exerts a force of 3 N on that wall, how much force does the wall exert back on the ball?

Answer 1

3N, Newton Third law of motion states that a a body will give you back the same force that you apply to it keeping the object in equilibrium until the maximum static friction is broken and the object starts moving. in this case the wall will not move by the force exerted by the ball, therefore, the wall will exert 3N on the ball.
