What is the radius of curvature of the first hill

Reference no: EM13493637

A roller coaster descends 35 meters in its initial drop and then rises 23 meters before going over the first hill. If a passenger at the top of the hill feels an apparent weight which is one half of her normal weight, what is the radius of curvature of the first hill? Assume no frictional losses, and neglect the initial speed of the roller coaster.
