(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 4 kg block moving to the right at 6 m/s collides elastically with a 2 kg block moving to the right at 3 m/s. Find the final velocities and the initial and final energies. Show all your work. [ignore external forces]

2. Relevant equations

In an elastic collision momentum inital = momentum final and KEi = KEf

momentum = mv

KE= .5mv^2

3. The attempt at a solution

I used these equations and did some algebra but ended up getting too many variables. Am i missing some info here?

Thanks.
