question_answer 34)

  A goalkeeper in a game of football pulls his hands backwards after holding the ball shot at the goal. This enables the goalkeeper to (a) exert larger force on the ball                                                (b) reduce the force exerted by the ball on hands (c) increase the rate of change of momentum                    (d) decrease the rate of change of momentum

Answer:

  (d) The goalkeeper pulls his hands backwards after holding the ball to decrease the rate of change of momentum by increasing the time. By doing this, less force is exerted on his hands (Force is directly proportional to the rate of change of momentum).
