Suppose Two Identical Objects Traveling Toward Each Other with the Same

Multiple Choice

Suppose two identical objects traveling toward each other with the same speed collide. According to the momentum-transfer principle, if we observe one of the objects to be at rest after the collision, the other object:

A) Must be at rest also.
B) Must rebound backward with its original speed.
C) Must rebound backward with twice its original speed.
D) Must continue forward with twice its original speed.
E) The process as described violates the principle.
