An object initially at rest on a horizontal OX axis explodes into two pieces . One piece moves just after explosion along the axis OX with a speed of 6m/s. What are the direction and the magnitude of the velocity of the second piece whose mass is three times that of the first?

momentum is conserved

the 2nd (larger) piece moves in the opposite direction at 1/3 the speed
