C14-2. As the large ring rotates, the operator can apply abreaking mechanism that binds the cars to the ring, whichthen allows the cars to rotate with the ring. Assuming thepassengers are not belted into the cars, determine thesmallest speed of the ring (cars) so that no passenger willfall out. When should the operator release the brake so thatthe cars can achieve their greatest speed as they slide freelyon the ring? Estimate the greatest normal force of the seaton a passenger when this speed is reached. Use numericalvalues to explain your answer.

The "flying car" is a ride at an amusement park which consists of a car having wheels that roll along a track mounted inside a rotating drum. By design the car cannot fall off the track, however motion of the car is developed by applying the car's brake, thereby gripping the car to the track and allowing it to move with a constant speed of the track, vt = 3 m/s. The rider applies the brake when going from B to A and then releases it at the top of the drum, A, so that the car coasts freely down along the track to B (0 = π rad). Neglect friction during the motion from A to B. The rider and car have a total mass of 390 kg and the center of mass of the car and rider moves along a circular path having a radius of R = 9.8 m.
