Suppose the position function for a free-falling object on a certain planet is given by s(t) = −16t2 + v0t + s0. A silver coin is dropped from the top of a building that is 1, 362 feet tall. Determine the average velocity of the coin over the time interval [1, 2]. −48 ft/sec −53 ft/sec 16 ft/sec 48 ft/sec −16 ft/sec
