Hi, I've started this question and just want to make sure that I'm along the right lines of completing it correctly because I'm getting really confused, thank you!


A body of mass 2.2 kg moving on a smooth horizontal surface at 3.5 m/s collides with a second body of mass 0.8 kg which is at rest. After the collision the bodies coalesce. Find the common speed of the bodies after impact.

The sum of the momentum of the separate bodies before collision is equal to the momentum of the combined body after collision.
