During a maneuver in space, a space craft separates into two pieces, each of mass m. before the separation, the spacecraft was moving with a speed v. if one of the pieces is at rest after the separation, which one of the following statements concerning this maneuver is true?
a) this maneuver conserves kinetic energy. b) the maneuver does not conserve total energy. c) this maneuver does not conserve momentum. d) if one piece is at rest, the other is moving with a speed 2v. e) one piece cannot be at rest. the must both be moving with a speed v/2.
