A ball is launched at the speed of 40 meters a second from an 89 meter tall platform. The equation for the balls height is h at a time t seconds after launch is h(t) = 4.9t^2 + 40t + 89 When will the ball hit the ground?

How long will it take the ball to reach maximum height

What is the balls maximum height
