You drop an object from the top of the CN Tower in Toronto, Ontario. The tower has a height of 1815 feet.
(a) Use the position equation to write a mathematical model for the height of the object.
(b) Complete the table.

(c) From the table in part (b), determine the time interval during which the object reaches the ground. Numerically approximate the time it takes the object to reach the ground.
(d) Algebraically find the time it takes the object to reach the ground. How close was your numerical approximation?
(e) Use a graphing utility with the appropriate viewing window to verify your answer(s) to parts (c) and(d).
Use the position equation given in Example 8 as the model for the problem.
