In order to catch a ball, a baseball player extends the hand forward before impact with the ball and then lets it ride backward in the direction of the ball's motion upon impact. doing this reduces the force of impact on the player's hand principally becaus

time of impact is increased

Explanation:

Whenever there is an interaction between two bodies, and at least one of them is moving, or acquiring movement, determining the amount of movement and momentum is important for studying the impact that the interaction between these two bodies will generate.

In any clash between two or more bodies, if we consider the system composed solely of them - therefore, without the existence of forces outside the system - there will always be the conservation of the amount of motion. We can consider this shock as an impact between two bodies and use as an example the impact between a baseball player's hand and the ball. To catch a ball, a baseball player extends his hand forward before impact with the ball and then lets it back in the direction of ball movement after impact. This reduces the force of impact on the player's hand, mainly because impact time is increased.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
