A ball travels on a parabolic path in which the height (in feet) is given by the expression -16t^2+48t+15, where $t$ is the time after launch. What is the maximum height of the ball, in feet?
Maximum height will occur when t = - b/2a where b = 48 a = -16
when you compute this value of 't' , put it into the equation to calculate the max height , 'h'
