Two rocks collide in outer space. Before the collision, one rock had mass 9 kg and velocity < 4700, -3100, 2300> m/s. The other rock had mass 5 kg and velocity < -400, 2200, 3600> m/s. A 3 kg chunk of the first rock breaks off and sticks to the second rock. After the collision the 6 kg rock has velocity < 1800, 650, 1500> m/s. After the collision, what is the velocity of the other rock, whose mass is now 8 kg
