Answer:
The ball exerts a force of 400 N on the bat.
Explanation:
Given that,
A baseball player hits a ball with 400 N of force.
We need to find the force the ball exert on the bat.
We know that,
According to Newton's third law, when object 1 exerts a force on an object 2, then object 2 will exert a force on object 1 but in opposite direction.
So, the ball exerts a force of 400 N on the bat.
