the height in feet of an object thrown upward is given by the equation
\n" ); document.write( "h(t) = 80t-16t^2, where h is the height of the object after t seconds. after how many seconds does the object reach it maximum height?
\n" ); document.write( "----
\n" ); document.write( "Max occurs when x = -b/2a = -80/(2(-16)) = 5/2 = 2.5 seconds
