At time t in seconds, an object's distance from a point is given by s(t) = \ ' t3 + 1 centimeters. (a) Find the average velocity of the object between t = 2 and t = 5 seconds. Give an exact answer and include units. Average velocity = 2.74 loentimeters per second VI (b) Use a difference quotient with h = 0.01 to estimate 5 '(2) . Give your final answer to three decimal places. 5 '(2) == 2.003 I centimeters V
