The roller-coaster track shown is contained in a vertical plane. The portion of track between A and B is straight and horizontal, while the portions to the left of 4 and to the right of B have radii of curvature as indicated. A car is traveling at a speed of 72 km/h when the brakes are suddenly applied, causing the wheels of the car to slide on the track ( 0.20). Determine the initial deceleration of the car if the brakes are applied as the car (a) has almost reached 4, (b) is traveling between A and B, (c) has just passed B.
