The position of an object moving along a line is given by the function s(t)= -9t² +90t. Find the average velocity of the object over the following intervals. (a) The average velocity of the object over the interval [1, 5] is 36 (b) The average velocity of the object over the interval [1,4] is 45. (c) The average velocity of the object over the interval [1, 3] is 54. (d) The average velocity of the object over the interval [1, 1+h] is
