At time tin seconds, an object's distance from a point is given by s(t) = 'f 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 = I -Select--- V I (b) Use a difference quotient with h = 0.01 to estimate s'(2) . Give your nal answer to three decimal places. so .
