Ok I have a physics question.
Yesterday my GF's car got stuck on some ice, the wheels kept spinning.
I put some cloths behind the wheels but still on the ice, and the tires got some traction on the cloth and she was able to reverse.
Now my question is.. why is this possible?
surely if the cloth is *on the ice* then the friction is the same and the cloth just slips instead of the tires.
basically the friction of a system should be equal to the lowest friction within the system and since the tires are made of high-friction rubber they should be better than the cotton cloth.
Why is that not the case?
