The rollercoaster track shown is contained in a vertical plane. The potion of track between A and B is straight and horizontal, while the portions to the left of A and to the right of B have radii of curvature as indicated. A car is traveling at a speed of 72km when the brakes are suddenly applied, causing the wheels of the car to slide on the track (H = 0.20). Determine the initial deceleration of the car if the brakes are applied at three locations: as the cars has almost reached A, is travelling between A and B, and as it just passed B. %3D p= 30 m p = 45 m

Transcribed Image Text:The rollercoaster track shown is contained in a vertical plane. The potion of track between A and
B is straight and horizontal, while the portions to the left of A and to the right of B have radii of
curvature as indicated. A car is traveling at a speed of 72km when the brakes are suddenly
applied, causing the wheels of the car to slide on the track (ux = 0.20). Determine the initial
deceleration of the car if the brakes are applied at three locations: as the cars has almost reached
A, is travelling between A and B, and as it just passed B.
