How do Newton's law of motion explain why it is important to keep the ice smooth on a hockey rink

The correct answer is "Smooth ice reduces the unbalanced forces that would slow down the hockey puck".

Explanation:

Newton's law of motion gives us a basis for understanding the behavior of action forces and reaction to a displacement situation.

Smooth ice reduces the unbalanced forces that would slow down the hockey disc, because if there were deformations in the ice there would be friction forces that would stop the movement making it difficult for the disc to move through the ice.
