A 1.6kg colt automatic pistol fires a 15g bullet into a 2.5kg block suspended as a ballistic pendulum. The bullet becomes embedded in the block 6.9x10^-4s after first contact. The bullet and block swing East to a height of 9.8cm from rest position. If pistol wasn't held firmly, what would be the recoil velocity?

I'm sorry I forgot to include what the answer was. On my answer sheet I'm told the velocity is 2.2m/s West. I cannot seem to get this answer myself.
