(2700 lbs * 2500 ft/s ) shell * 9 shells = 6.075 x 10**7 ft*lb/s

The mass of the ship is 57,000 tonnes * 2204 lb/tonne =1.25628 x 10**8 lbs

Divide the momentum of the one side (shells), by the mass of the other (ship), to get the initial velocity of the ship:

1.25628 x 10 **8
6.075 x 10** 7

~= 2.0 ft/sec

Two minor math errors that significantly affect the answer.

The combined momentum of the shells is 6.075x10**5 ft*lb/s vice 6.075x10**7 ft*lb/s.

You reversed the division from your statement. It should be:

6.075 x 10**5
1.25628 x 10**8

~= 4.849x10-3 ft/sec or ~6 hundredths of an inch.

I submit that this is insignificant when referring to a battleship.
