Do you think this is correct? Momentum and Recoil Velocity Calculations

[domyy]

Homework Statement

A rifle with a mass 2.2kg fires a bullet with a mass of 5g. The bullet moves with a velocity of 600m/s.

1) What is the momentum of the bullet after it´s fired?
2) What is the recoil velocity of the rifle assuming that no external forces act on the rifle?

Homework Equations

P = mv

The Attempt at a Solution

For question 1) P = 0.005kg x 600m/s = 3kg. m/s.

For question 2) I wrote 0.

Are my answers correct?
