Can you answer demonstration 4

Thank you!!

Demonstration 4: Two objects A and B, of equal mass, collide and bounce apart. One of the objects is initially traveling to the right, and the other object is initially at rest. In the lower half of the box on the right, draw the force(s) acting on each object as they collide (while they are in contact with each other). How do the magnitudes of these forces compare? Compare the momentum of either object just before the collision to its momentum just after the collision. Compare the total (combined) momentum of the two objects before the collision to their total momentum after the collision. After you have made your predictions, use the same Collision Lab simulation. First click Restart. Be sure the masses are equal and make velocityZ zero. The slide bar should again be set all the way to the right: Elastic collision. Click Play to run the simulation. You can click Pause to stop or Restart and Play to run the simulation again. Compare your results to your predictions. Explain any differences. Was momentum conserved? Explain
