Question a cannon of mass 650 x 103 kg is rigidly bolted to, Ask an Expert

Academics

Question: A cannon of mass 6.50 x 10³ kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 88.1-kg shell horizontally with an initial velocity of 551 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil.

Part A: What would be the velocity of a shell fired from these loose cannon?

I want help to find the velocity of a shell fired from these loose cannon and hint: In both cases assume that the burning gunpowder imparts the same kinetic energy to the system.
