Provide me the every step to evaluate the answer of the following problem

Problem- A marksman holds a rifle of mass 3.00 kg loosely in his hands, so as to let it recoil freely when fired. He fires a bullet of mass 5.00 g horizontally with a velocity 300 m/s.

Part A- What is the recoil velocity of the rifle?

Part B- What are the final momentum and kinetic energy of the bullet?

Part C- What are the final momentum and kinetic energy of the rifle?

I need help to formulate the answer of the above problem.
