A student throws a ball over a vertical wall of height h. The ball leaves the hand of the student at a height of 1.2 m above the horizontal ground with an initial velocity of 22 m s⁻¹ at an angle of 40° to the horizontal. The wall is a horizontal distance of 36 m from where the student releases the ball. Air resistance is negligible. (The time to reach the wall was found in (b)(i) and the vertical component of initial velocity in (b)(ii).)

The ball just goes over the wall.

Calculate the height h of the wall.
