Do I use the concept of elastic collision and its related linear momentum and velocity equations? That is how I've solved it and got 535 m/s. Ths velocity decreases because the potential energy is supplied to moving the cannon?

A cannon of mass 5.80x10° kg is rigidly bolted to the earth so it can recoil only
by a negligible amount. The cannon fires an 85.0-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. What would be the velocity of another
identical shell fired horizontally by this loose cannon? Assume that both
explosions produce the same amount of kinetic energy.
