A roller coaster goes through a loop-the-loop of radius 32m. If the cars are to barely remain on the track when upside down without any extra wheel on the other side of the track, what is the inimum speed required for the cars? (If the cars are barely staying on the track at the top, you will feel weightless. Therefore what will the normal force be at the top?)
