13. [-/7 Points] LARCALC11 2.2.095. MY NOTES DETAILS A silver dollar is dropped from the top of a building that is 1332 feet tall. Use the position function below for free-falling objects. s(t) = -1612 + Vot + 50 (a) Determine the position and velocity functions for the coin. s(t) = -161 + 1332 V(t) = (b) Determine the average velocity on the interval [3, 4]. ft/s (c) Find the instantaneous velocities when t = 3 seconds and t = 4 seconds. v(3) = ft / 5 V(4) = 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 Need Help? Read It
