A water balloon is launched at a speed of 21 m/s and an angle of 36 degrees above the horizontal. The water balloon hits a tall building located 7 m from the launch pad. At what height above the ground level will the water balloon hit the building? Calculate the answer in meters (m) and rounded to three significant figures.
