Rock a in the asteroid belt has a mass of 50 kg and is travelling at a velocity of 10 m/s.

rock b has a mass of 100 kg and is travelling at 7 m/s in the same direction as rock a. rock b has a momentum of 700 kg m/s. rock a and rock b collide and join together. calculate the velocity of the two rocks after the collision. show your working.
