A stationary 2000 Kg cannon fires a 25 kg cannonball horizontally at 250 m/s. Find the velocity of the cannon after firing the cannonball . You may assume friction is negligible.

2. Relevant equations

M1V1+M2V2=(M1+M2)V'

3. The attempt at a solution

(25)(250)+ (2000)(0)= (2000+25)V'

V'=(25)(250)/(2025)

V'=3.086 m/s

I just need confirmation as Im not 100% positive with my physics... thanks !
