A ball is thrown vertically from the ground and 3 ft away from one side of the building at a rate of 52.1 ft/s. After 0.51 second, a boy inside the building sees the ball passing thru the window, then reaches its maximum height, and finally fall back towards the ground. The boy’s eyes are aligned to the center of the window and his viewing angle equal to 60 degrees subtends the entire height of the window. Determine the height of the window. Draw free body diagram.
