ok, if someone started rolling down an escalator at lets say 5 mph and his speed increased at 10 mph every second. now the escalator is moving up at the same speed as the person falling. this happened until the escalator was going up at 200 mph and the person was rolling down at 200 mph. now if the escalator suddenly stopped, would the person come flying down the escalator at 200 miles per hour or would he just start rolling down according to the first equation, (starting 5 mph and his speed increased at 10 mph every second.)
