参考答案:
Consider this problem as a very light object
hitting and sticking to a very heavy object.
The large object – small object combination (Earth + jumper) would have
some momentum after the collision, but due to the very large mass of the Earth,
the velocity of the combination is so small that it is not measurable. Thus the jumper lands on the Earth, and
nothing more happens.
