(adsbygoogle = window.adsbygoogle || []).push({}); 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

Po=P

m1v1=m2v2

m=mass

3. The attempt at a solution

I keep trying to solve by using m1v1=m2v2

m2 = m1v1/v2
