The path of the coaster from its initial point shown in the figure to point involves only up-and-down motion (as seen by the riders), with no motion to the left or right. (a) If the vehicle has a speed of 20.0 m/s at point A, what is the force exerted by the track on the car at this point? (b) What is the maximum B 12 Figure P6.16 Problems 16 and 38
