Suva AIA ball is thrown from a point O, which is 6m above horizontal ground. The ball is projectd with speed u ms -1 at an angle θ above the horizontal. There is a thin vertical post which is 4m high and 8m horizontally away from the vertical through O, as shown in following figure. The ball passes just above the top of the post 2s after projection. Find the value of tanθ.
