The stopping distance for an automobile (after applying the brakes) is approximately F(s) = 1.15mr + 0.05432 ft. where s is the speed in mph. Use the Linear Approximation to estimate the change in stopping distance per additional mph when s : 45. (Use decimal notation. Give your answer to two decimal places.) Use the Linear Approximation to estimate the change in stopping distance per additional mph when s : TD. (Use decimal notation. Give your answer to two decimal places.) ft ft
