A silver dollar is dropped from the top of a building that is 1346 feet tall. Use the position function below for free-falling objects. s(t) = -16t² + vt + so (a) Determine the position and velocity functions for the coin. s(t) = -161² 1346 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) = ft/s -64 (d) Find the time required for the coin to reach the ground level. (Round your answer to three decimal places.) t = 9.17 S (e) Find the velocity of the coin at impact. (Round your answer to three decimal places.) 9.147 ft/s
