4.Determine if the Mean Value Theorem for Integrals applies to the function f(x) = x^3 9x on the interval [1, 1]. If so, find the x-coordinates of the point(s) guaranteed to exist by the theorem.

5.An object has a constant acceleration of 40 ft/sec2, an initial velocity of 20 ft/sec, and an initial position of 10 ft. Find the position function, s(t), describing the motion of the object.
