The height of an object t seconds after it is dropped from a height of 300 meters is s(t) = −4.9t2 + 300. (a) Find the average v
elocity of the object during the first 6 seconds. -78.4 m/s (b) Use the Mean Value Theorem to verify that at some time during the first 6 seconds of fall, the instantaneous velocity equals the average velocity. Find that time. 2.1 s
