<PRE><B>Question 1029104</B>
 Let&#39;s look at another one of homer&#39;s rocket launches. It was launched from ground level with an initial velocity of 208 feet per second. its distance in feet from the ground after t seconds is given by S(t)= -16t^2+208t. 
What is the maximum altitude (height) the rocket ail attain during its flight?
------
Max occurs when t = -b/(2a) = -208/(-32) = 6.5 seconds
----
Max height is S(6.5) = 676 ft.
