I need help with this section of my worksheet

3. A ball of mass 25 g traveling east at 12 m/s bounces elastically into a 2nd ball of mass 50
g that is traveling west at 4m/s. What are the final velocities and momentum of each
ball? (Hint: either solve the systems of equations for momentum and energy
simultaneously or come up with a relative velocity system.)
Place ball 2 in a moving reference frame so that it's velocity is O in this reference frame.
In this reference frame ball 1 has 16 m/s initial velocity. Find the final velocities in this
moving reference frame.
