The stopping distance for an automobile (after applying the brakes) is approximately F(s) = 1.1s + 0.054s2 ft, where s is the speed in mph. Use the Linear Approximation to estimate the change in stopping distance per additional mph when s = 40. (Use decimal notation. Give your answer to two decimal places.) AF Use the Linear Approximation to estimate the change in stopping distance per additional mph when s = 65. (Use decimal notation. Give your answer to two decimal places.) ft
