- Using the Position Equation In Exercises 111-114, use the position equation given in Example 8 as the model for the problem. An aircraft flying at 550 feet over level terrain drops a supply package. (a) How long does it take the supply package to strike the ground ? (b) The aircraft is flying at 138 miles per hour. How far does the supply package travel horizontally during its descent ?arrow_forwardUsing the Position Equation In Exercises 111-114, use the position equation given in Example 8 as the model for the problem. 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.arrow_forwardUsing the Position Equation In Exercises 111-114, use the position equation given in Example 8 as the model for the problem. Some Major League Baseball pitchers can throw a fastball at speeds of up to and over 100 miles per hour. Assume a Major League Baseball pitcher throws a baseball straight up into the air at 100 miles per hour from a height of 6 feet 3 inches. (a) Use the position equation to write a mathematical model for the height of the baseball. (b) Find the height of the baseball after 4 seconds, 5 seconds, and 6 seconds. What must have occurred sometime in the interval 4t6? Explain. (c) How long is the baseball in the air ?arrow_forward
