The magnitude of the force that a baseball bat exerts on a ball is 50. newtons. The magnitude of the force that the ball exerts on the bat is
50N
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that if the baseball bat exerts a force on the ball, the ball will exert an equal but opposite force on the bat.
Therefore, the magnitude of the force that the ball exerts on the bat is also 50 newtons.
