A 5.4 kg ball of blue clay is observed moving at 0.64 m/s aimlessly through space (as seen by a nearby alien spacecraft) and collides and sticks to a 2.3 kg ball of red clay that is initially at rest (relative to the aliens). The two balls of clay stick together and coast off together. What speed to the aliens observe the purple clay moving away at?
