A silver dollar is dropped from the top of a building that is 1399 feet tall. Use the position function below for free-falling objects.
s(t) = 16t2 + v0t + s0
(a) Determine the position and velocity functions for the coin.
s(t) = |
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/s |
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 = s (e) Find the velocity of the coin at impact. (Round your answer to three decimal places.) ft/s
