A car is traveling around a circular banked road without friction which is inclined at 24 degrees. When the car is traveling at 18.2 m/s around the road, it is moving at the bottom on the incline (inner radius of the road when viewed from an aerial view). When the car is traveling at 36.6 m/s, it is moving at the top of the incline (outer radius of the road when viewed from an aerial view). What is the vertical height of the road in meters? (Ignore the width of the car when doing this problem.)
