A ball is thrown from the edge of the top of a building with an initial velocity of 80.3 km/hr at an angle of 52.5 degree above the horizontal. The ball hits the ground a horizontal distance of 108 from the base of the building. Assume that the ground is level and that the side of the building is vertical. Calculate the height of the building.
"h=H-h_0=20 .7~m."
