Aball strikes a wall. it exerts a force of 10 n to the left against the wall and bounces off. what force does the wall exert on the ball?

For this case, when the ball bounces, we can make a free-body diagram in a horizontal direction, obtaining:

-10 + F = 0

Where,

F: force that the wall exerts on the ball.

Clearing the value of F we have:

F = 10 N

Therefore, the wall exerts a force of 10 N on the ball, and the direction of the force is to the right.

the wall exerts 10N on the ball to the right
