Consider a roller coaster as it travels near the bottom of its track as sketched in the figure below. At this point, the normal force on the roller coaster is five times its weight. If the speed of the roller coaster is 26 m/s, what is the radius of curvature of the track?

Consider a roller coaster as it travels near the bottom of its track as sketched in Figure. At this point, the force on the roller on the coaster is three times its weight. If the speed of the roller coaster is 20 m/s, what is the radius of curvature of the track?
