A roller-coaster car has a mass of 495 kg when fully loaded with
passengers. The path of the coaster from its initial point shown in
the figure to point B involves only up-and-down motion (as seen by
the riders), with no motion to the left or right. Assume the
roller-coaster tracks at points circled A and circled B are parts
of vertical circles of radius r1 = 10.0 m and r2 = 15.0 m,
respectively.
(a) If the vehicle has a speed of 21.0 m/s at point ,
what is the force exerted by the track on the car at this
point?
