A ball travels on a parabolic path in which the height (in feet) is given by the expression −16t^2+60t+21, where t is the time after launch. What is the maximum height of the ball?

The TIME when the ball reaches maximum height is found by  t = - b/2a     a =-16   b = 60

  use THIS value of time in the equation to find the max height....
