2. A boy staying on the 7th floor drops a pebble down. At the same time another boy who stays on the 13th floor throws another pebble with an initial downward velocity of 10 m/s. If both pebbles are in the same vertical path, find out whether the pebbles will collide before they hit the ground. If they collide, find out at which height from ground they collide. 18 m 36 m
