The roller coaster in the figure below starts with a velocity of16m/s.One of the riders is a small girl of mass 27kg.Find her apparent weight when the roller coaster is at locationsBandC. At these two locations, the track is circular, with the radii of curvature given in the figure. The heights at points A, B, and C are hA=23m, hB=33m, and hC= 0. Assume friction is negligible and ignore the kinetic energy of the wheels.
