The height in feet of a free falling object t seconds after release is , s(t) = -16t2 + v0t + s0, where is the height (in feet) at which the object is released, and Vo is the initial velocity (in feet per second). Suppose a coin is dropped from the top of the Empire State Building in New York, which is 1454 feet tall.

A. Determine the position and velocity functions for the coin.

B. Determine the average velocity of the coin on the interval [1, 3].

C. Find the instantaneous velocities when t = 1 and t = 3.

D. At what time is the instantaneous velocity of the coin equal to the average velocity of the coin found in Part B?

E. What is the name of the theorem that says there must be at least one solution to Part D?

F. Find the velocity of the coin just before it hits the ground.
