A soccer goalkeeper is standing in front of his side goal-post. An opposite side player shoots the ball(mass=0.25kg) towards the goalkeeper with the a velocity of 40m/s. The goalkeeper kicks back the ball towards the opposite side player with a velocity of 61 m/s. The ball was in contact with the goalkeeper’s leg for about 0.5seconds. What is the average force exerted on the goalkeeper by the ball?
