Lottery balls are thrown into a hopper and are set into motion by air forced through the container. each ball has a mass of 0.0044 kg. at one instant in time, ball 1 is moving upward with a speed of 1.3 m/s, and ball 2 is moving downward with a speed of 1.66 m/s. if the kinetic energy of the three-ball system at this instant is 0.0268 j, what must be the speed of ball 3?
