An isolated system contains two bodies on which no external forces are acting. The two bodies collide with each other and remain joined after the impact. Which row gives the correct comparison of the total kinetic energy and the total momentum of the bodies before and after the collision?
- Atotal kinetic energy before and after the collision: different; total momentum before and after the collision: different
- Btotal kinetic energy before and after the collision: different; total momentum before and after the collision: the same
- Ctotal kinetic energy before and after the collision: the same; total momentum before and after the collision: different
- Dtotal kinetic energy before and after the collision: the same; total momentum before and after the collision: the same
