Extracted text: The curve portion of a road is defined by y= where x and y are in feet. Determine (a) the 106 radius of of curvature pand (b) the magnitude of the normal acceleration a, of a car moving with a constant speed of 40 ft/s when it is at point x = 600 ft. x3 106 40 ft's 600 ft 2. A car travels around a circular track at 16 m/s. As soon as it reaches point Pit accelerates at a, = 3 m's, where v is in m/s. Determine the magnitude of the velocity and acceleration of the car as it reaches point Q. 200 m
