The height, $h$ meters, of a projectile above the ground at a horizontal distance of $x$ meters from the launch point is modelled by the function $h(x) = -0.02x^2 + 1.2x + 3$, where $x \ge 0$. This model is valid until the projectile hits the ground.
a. Determine the horizontal distance from the launch point at which the projectile reaches its maximum height. Find also the maximum height reached.
