# A firework shell of mass \(M\) is moving upward at speed \(v_0\) when an internal explosive charge detonates, bursting the shell into several fragments over an infinitesimal time interval \(\Delta t\). If the impulse delivered by gravity during the detonation is negligible compared to the internal explosive forces, which of the following correctly describes the total linear momentum and the total kinetic energy of the system of fragments immediately after the explosion compared to immediately before?

A firework shell of mass \(M\) is moving upward at speed \(v_0\) when an internal explosive charge detonates, bursting the shell into several fragments over an infinitesimal time interval \(\Delta t\). If the impulse delivered by gravity during the detonation is negligible compared to the internal explosive forces, which of the following correctly describes the total linear momentum and the total kinetic energy of the system of fragments immediately after the explosion compared to immediately before?

- **A.** Total linear momentum is conserved, and total kinetic energy is conserved.
- **B.** Total linear momentum is not conserved, and total kinetic energy increases.
- **C.** Total linear momentum is conserved, and total kinetic energy increases.
- **D.** Total linear momentum is not conserved, and total kinetic energy is conserved.
