The roller coaster in Figure P6.36 starts with a velocity of 15.4 m/s. One of the riders is a small girl of mass 30 kg. Find her apparent weight when the roller coaster is at locations B and C. 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= 24.85 m, hB = 34.2 m, and hC=0 m.
