A 5 kg rock is shot vertically upwards at 10 m/s. At 5 m above ground, it breaks into two pieces of masses 2 kg and 3 kg. The 3 kg-piece moves horizontally with a velocity of 2 m/s immediately after breaking. Calculate the horizontal distance between the initial point where the 5 kg rock is shot and the landing point of the 2 kg-piece
