Question

golf ball and an equal-mass bean bag are dropped from the same height and hit the ground.The bean bag stays on the ground while the golf ball rebounds. Which experiences the greatest from the ground? A) The golf ball. B) The bean bag C) Both the same. D) The ground. E) Not enough information.

Answer 1

Option A is correct because change in momentum of half ball is greater than the bag

I = Delta p (change in momentum) Delta P_gb = m v_gb - (-m v_gb^!) = m (v_gb + v_gb^!) Golf ball v_gb = Initial velocity v_gb^! = final velocity Bean Bag Delta P_B = m v_B v_B = Initial velocity of Bean Bag Delta P_gb > Delta P_B Change in momentum of golf ball is larger than the change in momentum of bean bag. So, option (A) is correct.
