A baseball player up to bat gets hit by a fast ball. What is the predominant type of force generated by the ball on the player? Explain your reasoning.

Reaction force

Explanation:

According to Newton's third law of motion, for every action, there is an equal opposite reaction.

Hence the reaction force is often equal in magnitude to the applied force but acts in a direction opposite to the direction of the applied force.

Hence, when a baseball player, gets a hit, the ball exerts a reaction force on the player which is equal in magnitude to the force with which the player hits the ball but opposite in direction.

the independent variable, or the one that is intentionally manipulated is the speed.

the bal will not change its velocity.
