Suppose that an object is moving along a vertical line. Its vertical position is given by the equation L(t) = 4t2 - 4t + 8, where distance is measured in meters and time in seconds. Find the approximate value of the average velocity (accurate up to three or more decimal places) in the given time intervals. m between t1=2 s and t2=8 s : between t1=3 s and t2=5 s : between t1=4 s and t2=9 s : Submit
