You are walking on fixed ground at 5mph, with a roller-caster pulled from the leg of a chair in your right hand.
As you move, you lean on a plain, flat wall to your side with this caster so the wheel in it spins.
If the wall starts moving at 5mph in the opposite direction that you are travelling, will you stop moving forward?
