Question

a baseball thrown by a pitcher is hit by a batter. at the moment when the ball hits the bat, the force exerted on the bat by the ball is $f_{ball\\ on\\ bat}$ and the force exerted on the ball by the bat is $f_{bat\\ on\\ ball}$. the relationship between these forces is ____________. (1 point)
$f_{ball\\ on\\ bat}=-f_{bat\\ on\\ ball}$
$f_{ball\\ on\\ bat}$f_{ball\\ on\\ bat}>f_{bat\\ on\\ ball}$
$f_{ball\\ on\\ bat}=f_{bat\\ on\\ ball}$

Explanation:

Step1: Recall Newton's third - law

Newton's third - law states that for every action, there is an equal and opposite reaction. When the ball exerts a force $F_{ball\ on\ bat}$ on the bat, the bat exerts a reaction force $F_{bat\ on\ ball}$ on the ball. The two forces are equal in magnitude and opposite in direction.

Answer:

$F_{ball\ on\ bat}=-F_{bat\ on\ ball}$
