Two rocks collide in outer space, before the collision one rock had a mass 12kg and velocity (4200,-2700,2450)m/s. The other rock has a mass of 7kg and a velocity (-700,2200,3650)m/s. A 2kg chunk of the first rock breaks off and sticks to the second rock. After the collision, the 10kg rock has velocity (1500,350,1950)m/s. After the collision what is the velocity of other rock whose mass is now 9kg?
