Question

1.(a) Alice says Cathy’s body has zero momentum, but Bob
says Cathy’s momentum is nonzero. Nobody is lying or making a
mistake. How is this possible? Give a concrete example.
(b) Alice and Bob agree that Dong’s body has nonzero momentum,
but disagree about Dong’s angular momentum, which Alice says is
zero, and Bob says is nonzero. Explain.
2.Two objects have the same momentum vector. Assume that they are not spinning; they only have angular momentum due to their motion through space. Can you conclude that their angular momenta are the same? Explain. [Based on a problem by Serway
and Faughn.]

nothing missing!! the question is complete and from the book!!

this might help

Answer 1

5.) a) It is possible if Alice and cathy is in same frame of reference (moving frame) whereas bob is in rest frame example! Alice and cathy is sitting in moving bus where as bob is at rest on ground u it is but bob of Dong possible is standing Dong is moving to away from toward Alice line I motion Domen-obelice -- Bob----- 6-) No be Non because angulas momentum is defined as product g distalement vectos and momentem veelous and Since nothing is said about this displacement vectors hence we can't say that it's angulas momentum are ам.
