A car C is traveling up a spiral ramp at a constant and traveling as fast as it can without losing traction. The grade of the ramp is and the effective radius of curvature (while on the ramp) is . Once the driver exits the ramp and is at A (straight, level road) what maximum acceleration will he be able to attain? (Hint: Use the data for the ramp to determine the road's cofficient of friction and then use this value in determining the car's acceleration on the straightaway.)
