2. Consider the egg from problem 1 as it strikes the ground. How would you describe the change in the momentum of the earth-egg system due to the collision of the egg the ground and consider "after collision" to be at a point when all of the parts of the a. The momentum of the system decreases, since the egg has momentum just with the ground? Neglect air resistance. Assume that the egg breaks on impact with egg are motionless with respect to the ground. before impact but is motionless afterward. b. The momentum of the system increases, since the egg was released from rest but it is moving with some speed at the moment of impact c. The momentum of the system is unchanged. The two bodies in the system are initially at rest with respect to their common center of mass. They fall towards their common center of mass after the egg is released. The force of the impact brings both bodies to rest again. d. There is not enough information to answer the question. O The momentum of the system decreases, since the egg has momentum just before impact but is motionless afterward. O The momentum of the system increases, since the egg was released from rest but it is moving with some speed at the moment of impact. The momentum of the system is unchanged. The two bodies in the system are initially at rest with respect to their common center of mass. They fall towards their common center of mass after the egg is released. The force of the impact brings both bodies to rest again. There is not enough information to answer the question

Explanation / Answer

By law of conservation of momentum, momentum of a system is always conserved, irrespective of the type of collision.

Thus the correct answer is option (c).
