If you're familiar with calculus, find where and then plug that value into the original function to find the maximum height. Otherwise, you can use the fact that the vertex of a parabola occurs at the point
thanks for reply, vertex of a parabola looks more familiar, where do i go next?

confirmed? horizontal distance = 100 vertical distance = 55 is this correct?
