how many seconds after the rocket is launched does it reach maximum height? What is maximum height? How long until it hits the ground?

The height of a ball at a given time can be modelled with the quadratic function h(t) = -5+20t+1, where height, h(t), is in metres and time, t, is in seconds. How long is the ball in the air...
