An object is thrown towards the tower which is at a horizontal distance of 50 m with an initial velocity of 10 ms^(-1) and making an angle 30^(@) with the horizontal. The object hits the tower at certain height. The height from the bottom of the tower, where the object hits the tower is (Take, g = 10 ms^(-2))
