Two rocks collide in outer space. Before the collision, one rock had mass 15 kg and velocity ‹ 4300, ?2700, 2350 › m/s. The other rock had mass 8 kg and velocity ‹ ?600, 2100, 3750 › m/s. A 2 kg chunk of the first rock breaks off and sticks to the second rock. After the collision the 13 kg rock has velocity ‹ 1400, 250, 1900 › m/s. After the collision, what is the velocity of the other rock, whose mass is now 10 kg?
