A 6500 kg freight car traveling at 2.5 m/s collides with an 8000 kg stationary freight car if they interlock upon collision find thier velocity

2. Relevant equations

M1 = 6500

M2 = 8000 kg

V1 = 2.5 m/s

V2= ?

i think the equation is p before = p after but im confused how i can use it

3. The attempt at a solution

not sure how to use the equation
