You have been hired to design a roller coaster and are working on two sections. The roller coaster rolls on the track, but is not attached.
If the cars will have a speed of 35 m/s at the bottom of the hill, what is the radius that the circular bottom section of the track should have so that the seat exerts a force of 3800 N on an 80 kg rider?
