Since the cannon is placed on a smooth surface , after firing it will recoil , thus apply the conservation of momentum to find the velocity of the cannon.
Mass of cannon x velocity of cannon = mass of shell x velocity of shell
Mass of cannon = (1/50) m/s
Now since cannon and shell are moving away from each other we will add their speed to find the total distance
((1/10) + (1/50)) x time = distance covered
distance = 6x5/50 = 30/50 = 3/5 = 0.6m
