An ice hockey player skates towards the wall of an ice rink and slams into it. Which of these is not an action-reaction force pair that affects the hockey player?
A. He hits the wall and the wall hits him back with the same magnitude of force.
B. The weight of the hockey player is balanced by the normal force pushing on his skates.
C. The hockey player's weight is equal in magnitude to the frictional force acting on his skates.
The third one is incorrect. That's why hockey is played on ice. The effects of friction hare held to a minimum. So C is the answer. His weight is much more than the frictional force.
B is true and so is A, both for the action reaction force.
