A silver dollar is dropped from the top of a building that is 1312 feet tall. Use the position function below for free-falling objects.
s(t) = -16t +Vgt + So
(a) Determine the position and velocity functions for the coin.
s(t) =
- 16r + 1312
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 ti me required for the coin to reach the ground level. (Round your answer to three decimal places.)
t =|-82
X S
(e) Find the velocity of the coin at impact. (Round your answer to three decimal places.)
