Consider a moving object whose position function is given by s(t) t 2 , where s is measured in meters and t is measured in minutes.

a. Determine the most simplified expression for the average velocity of the object on the interval [3, 3 + h], where h > 0. b. Determine the average velocity of the object on the interval[3, 3.2]. Include units on your answer. c. Determine the instantaneous velocity of the object when t 3. Include units on your answer.
