A silver dollar is dropped from the top of a building that is 1400 feet tall. Use the position function below for free-falling objects. s(t) = -16t2 + vot + So (a) Determine the position and velocity functions for the coin. s(t) = -161 + 1400 v(t) = -32t (b) Determine the average velocity on the interval [1, 2]. -48 ft/s (c) Find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = |-32 ft/s v(2) = -64 ft/s (d) Find the time required for the coin to reach the ground level. (Round your answer to three decimal places.) t = (e) Find the velocity of the coin at impact. (Round your answer to three decimal places.) ft/s
