A spaceship of mass 1.90×106 kg is cruising at a speed of 4.60×106 m/s when the antimatter reactor fails, blowing the ship into three pieces. One section, having a mass of 4.60×105 kg , is blown straight backward with a speed of 2.30×106 m/s . A second piece, with mass 8.20×105 kg , continues forward at 1.20×106 m/s . What is the speed of the third piece?
