To anticipate the dip and the hump in the road, the driver of a car applies his brakes to produce a uniform deceleration. His speed is 100kph at the bottom A of the dip and 50 kph at the top C of the hump. The length of the road from A to Cis 120m. The radius of curvature of the hump at Cis 150m. The total acceleration at A is 3 m/s^2. Compute the radius of curvature at A. 60 m 60 m A
