Homework Statement
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.
Homework Equations
M1V1+M2V2=(M1+M2)V'
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 I am not 100% positive with my physics... thanks !
