Question
A shell explodes while at rest. Discuss the momentum and energy conservation in the explosion.
✓

Answer

As the shell explodes, while being at rest, the momentum after explosion should also be zero. The internal energy with the shell will provide kinetic energy to the pieces into which it is broken. Therefore, there is increase in kinetic energy at the loss of internal energy.
