The Sidewinder is a shuttle type steel rollercoaster. The rollercoaster cart starts at the bottom of the frictionless track and is accelerated from a stand still over a distance of 7 meters. Then the cart enters the loop, rises to the top with just enough velocity to keep from stalling at the top of the loop. Gaining velocity the cart finishes the loop, bottoms out, and then rises up the vertical segment of the track. After stalling out at a...
