A boy stands at the top of the building, with height h above the ground, and throws a ball. The ball lands 30 m from the building at an angle of 600 with respect to the horizontal ground after 2.3 s. Find the height of the building. Find the initial velocity at which the ball is thrown and its angle of projection. What is the maximum height reached by the ball?
