A spaceship of mass 2.0*106 kg is cruising at a speed of 5.0*106 m/s when the antimatter reactor fails, blowing the ship into three pieces. One section, having a mass of 5.0*105 kg, is blown straight backward with a speed of 2.0*106 m/s. A sec-ond piece, with mass 8.0*105 kg, continues forward at 1.0*106 m/s. What are the direction and speed of the third piece?
