As you catch a fast-moving fastball, why is it wise to move your hand in the direction of the ball's motion? Explain in terms of work and energy


As you catch a fast-moving fastball, why is it wise to move your hand in the direction of the ball's motion? Explain in terms of work and energy

Step 1

As the hand is moved in the direction of motion of ball, actually will increase the time taken by the ball to stop will increase. Since the change in velocity occurs in greater time interval, it will decrease the force exerted by ball on the hand.

Step 2

Work done by hand is the dot product of force and displacement. Time has no any role in it. It means that work done will be the same in cases of longer or shorter time intervals to stop it. But the energy transferred would be different. More the time taken to ...
