Question

10
a hockey player is wearing ice skates and pushes against the wall propelling her backward on the ice. according to newtons third law of motion, which of the following best compares the forces acting between the wall and the hockey player?
a. the forces are equal and applied against gravity.
b. the forces are different sizes and applied in the opposite direction.
c. the forces are equal and applied in the opposite direction.
d. the forces are equal and applied in the same direction.

Explanation:

Newton's third law of motion states that for every action, there is an equal and opposite reaction. When the hockey player pushes on the wall (action force), the wall exerts an equal force back on the player in the opposite direction (reaction force), which propels the player backward. This matches option C.

Answer:

C. The forces are equal and applied in the opposite direction.
