The height of an object t seconds after it is dropped from a height of 140 meters is s(t) = -4.9t² + 140. (a) Find the average velocity of the object during the first 5 seconds. m/s (b) Use the Mean Value Theorem to verify that at some time during the first 5 seconds of fall, the instantaneous velocity equals the average velocity. Find that time. S
