The stopping distance D of a car after the brakes have been applied is directly proportional to the square of the speed s. The stopping distance o a car on dry asphalt is given by the function f(s) = 0.033s², s > 0, where s is measured in mi/h. (a) Find the inverse function of f. f-1(D) = ,D2 0 (b) Interpret the inverse function. The inverse function gives the ---Select--- that a car was going for a ---Select--- O of D. (c) If a car skids 46 ft on dry asphalt, how fast was it moving when the brakes were applied? (Round your answer to one decimal place.)
