# Man and particle

Classical Mechanics Level pending

A particle of mass $$m$$ moves with a uniform speed $$V_2$$ in a circle of radius $$R$$, centered at $$(R,0)$$ in the $$x-y$$ plane. A person moves along the $$y$$-axis with a uniform velocity $$V_1$$. At $$t= 0$$, the man as well as the particle are located on the $$x$$-axis and moving in the same direction. Find the angular momentum of this particle with respect to the man at the time $$t = \dfrac{\pi R}{2V_2}$$.
