thanks.
I figured it out.

here I have one more question.

Q.If a particle of mass m is moving with constant velocity v parallel to x-axis in x-y plane , calculate its angular momentum with respect to origin at any time t.

a) 2 feet

Are these, by any chance, from HC Verma?

yes, these are from H C Verma, but the answers given are
a)


b)

bob,
I think I need some more help with it.
