Why is it a good idea to extend your hand forward when catching a fast-moving baseball with your bare hand?
The reason behind extending hand forward while catching a fast-moving baseball with bare hands.
Answer to Problem 8RQ
The reason behind extending a hand forward while catching a fast-moving baseball with bare hands is that it creates move space to move hands in backward direction to increase the time of contact, which results in less force.
Explanation of Solution
Impulse is a quantity that is can be evaluated by multiplying applied force and the time of interaction. For a given amount of impulse generated, if the time of duration is increased, the impact force due to impulse will be less.
It is suggested to extend a hand in the forward direction, while catching a fast-moving baseball with hands, because it creates move space to hands, in order to move in the backward direction. When a player catches baseball, he/she moves hands in backward direction to increase the time of contact, and thus it decreases the amount of force. As the force exerted by baseball on hands is less, it will cause less injury.
Conclusion:
Therefore, the reason behind extending a hand forward while catching a fast-moving baseball with bare hands is that it creates move space to move hands in backward direction to increase the time of contact, which results in less force.
