Use the position equation given below, where 5 represents the height of the object (in feet), v0 represents the initial velocity of the object (in feet per second), sa represents the initial height of the object (in feet), and t represents the time (in seconds), as the model for the problem. 5 = 16t2 + v0: + so 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. (in) Complete the table. Time, r{sec) Height, 3 (ft) (c) From the table in part (b), determine the time interval during which the object reaches the ground. 0 The object reaches the ground between t = 2 and t = 4 seconds. 0 The object reaches the ground between t = 4 and t = 6 seconds. 0 The object reaches the ground between t = 6 and t = 8 seconds. 0 The object reaches the ground between t = 8 and t = 10 seconds. 0 The object reaches the ground between t = 10 and t = 12 seconds. Numerically approximate the time it takes the object to reach the ground. Use a graphing utility with the appropriate viewing window to verify your answer. (cl) Find the time it takes the object to reach the ground algebraically. Use a graphing utility with the appropriate viewing window to verify your answer. (Round your answer to two decimal places.)
