Hi there. I need help answering part (b) and (d) where the red X's are. I have attached a screenshot of the question. Thanks.

A coin drops from the top of a 1327-foot tall building. Use the position function below for free-falling objects. s(t) = 16t2 + vot + so (a) Determine s(t) and v(t) for the coin. Sm = 16t2 + 1327 I v(t) = 32t ., (b) Find the average velocity on the interval [1, 2]. Ex ft/s (c) Find the instantaneous velocities when t = 1 second and t = 2 seconds. 1) = m 2) = m (d) Find the time required for the coin to reach the ground level. (Round your answer to three decimal places.) t= 9.10700 V 5 Find the velocity of the coin at impact. (Round your answer to three decimal places.) :lx ft/s
