Help! Conservation of Momentum
1. The problem statement, all variables and given/known data
Object 1 has a mass of 2.8 kg and is moving eastward with a velocity of 7.7 m/s. It collides with a stationary object. After the collision object 1 recoils with a velocity of -2.2 m/s What is the mass of object 2?
2. Relevant equations
As far as I know:
Conservation of Momentum
3. The attempt at a solution
I keep trying to solve by using m1v1=m2v2
m2 = m1v1/v2

What does conservation of momentum mean in words?
What does the momentum equation you've written (m1 v1 = m2 v2) mean (in words)?
