1by energy conservation we can see that that the each bullet will go a max height of 20m ( v^2/2g) and then come back.
so by the time a bullet reaches its max height another bullet is being shot...and 7th bullet is shot after 6 s....
so i think 7th bullet will meet 1 while going up and 1 while coming down...waiting fr someone to give proper answer...
