Question
Explain how momentum conservation explains explosion of a mass at rest.
✓
Answer
Exploding mass is initially at rest. The momentum is zero. When the explosion takes place, since there is no external force acting, the momentum associated with all parts should vectorially add up to zero. The velocity associated with each part is due to the conversion of internal energy into kinetic energy.
