A strange quantum event occurs involving a 3 kg ball of cheese that splits into two 0.5 kg balls of chocolate. Momentum and Energy are conserved.
1. In the rest frame of the cheese ball what are the velocities of the chocolate balls?
2. What is the momentum of each chocolate ball?
3. What is the velocity of one chocolate ball relative to the other?
