Question

player catching a moving ball moves his hand backward why​

Answer 1

Answer:

Momentum

Explanation:

When something goes at a high speed it has a great force witch causes momentum so when it hits something that is not as strong as the force it will move it or in this case bend his hand backwards.

Answer 2

Answer:

Because while the ball is moving at a great speed and hits a stationary object that is at rest, then to reduce the velocity of ball to 0 in a short period of time the player moves his hand backwards
