title:    Loop the Loop

A ball is released at some height and allowed to roll into the loop.   If it has sufficient speed, the ball will make it all the way through the loop without leaving the track.
   A "hot wheels" version can also be set up.

   Calculate the height from which the ball needs to be placed to make it through the loop.  Would the answer be the same for a hot wheels car?
