Explain how to solve the following question in words. Then, provide the complete solution based on your description above. If an object is dropped from an 80-meter-high window, its height y above the ground at time t is given by the formula y = f(t) = 80 − 4.9t^2. Find the average velocity of the object between (a) t = 1 sec and t = 1.5 sec.
