a small spacecraft of mass m is moving in a straight line at a speed of 8.00m/s.It suddenly breaks into pieces .one piece of mass m/3 moves of with a velocity of 2.00m/s at an angle of 30 degrees to the original motion.Calculate the velocity as a vector of the other piece of the spacecraft

1 answer

The VECTOR sum of the momenta of the two pieces must equal the inital momentum of the entire spacecraft.
