the brakes have released, and the negative acceleration has ended, giving a slight positive acceleration and you jerk back.
you are talking about a positive acceleration but i have seen or observe that once wheel stop...wheel stay at their position w.r.t. rail.........when wheel is not moving so there is no possibilities of positive acceleration
just give a reason.
