An object is thrown at an initial angle of 30 degrees abovehorizontal with an initial speed Vi from the top edgeof a building that is 40 meters tall. The object lands at ahorizontal distance Xf = 80 meters from the building.You must show all your coordinate systems, calculations, and stepsto get full credit. Any formula that is not oneof the 5 fundamental kinematics equations must be derived. Find Theinitial speed (Vi) of the object. (10 points)
