Question

A goalkeeper. In a game of football pulls his
hands backwards -after holding the ball
shot at the goal. This enable . the goal
keeper to,​

Answer 1

Answer:

Decrease the force on his/her hand.

Explanation:

Let me explain you:

F=(p2-p1)/t

F*t=(p2-p1)

{Now call (p2-p1) with a new name, i.e. (delta p) and take is as a constant value}

F*t=delta p

{You can see in this case that force and time are inversely proportional, that is with force decreases time increases and with time increase force decreases}

Ans. That's why the goalkeeper pulls his hand backwards thus increasing the time and decreasing the force on his hand.

Read the solution carefully to understand.

Answer 2

Answer:

d. to decrease the rate of change of momentum

Explanation:

as rate of change of momentum is directly proportional to force the force exerted on the hand of the goalkeeper will be less
