To find the maximum height reached by the ball, we need to use the equation of motion under gravity: v^2 = u^2 + 2as, where v is the final velocity (which is 0 at the maximum height), u is the initial velocity, a is the acceleration due to gravity (-9.8 m/s^2), and s is the displacement. Rearranging the equation, we get s = u^2 / 2a = (20)^2 / (2 * 9.8) = 20.4 m.
