Let's design a roller coaster. It should consist of a long ramp leading into a loop. The loop should have a radius r of 7.2 m. The cars have a mass M of 211 kg. Assuming that friction can be neglected here, what should be the minimum height h of the ramp (in m) with respect to the bottom of the loop so that the cars don't fall off the track at the top of the loop
