The distance s (in feet) covered by a motorcycle traveling in a straight line and starting from rest in t sec is given by the function s(t) = −0.1t3 + 2t2 + 27t (0 ≤ t ≤ 3) Calculate the motorcycle's average velocity (in ft/sec) over the time interval [2, 2 + h] for h = 1, 0.1, 0.01, 0.001, 0.0001, and 0.00001. (Round your answers to four decimal places.)
