Extracted text: Three identical point masses of m = 0.3 (kg) are moving at a constant velocity v =10 (m/s) equidistant from each other on a circular orbit of radius R= 0.2 (m). What is the total angular momentum (kg.m/s) of the three point masses relative to point A at the moment shown in the figure. Point A is 2R away from the center. m 2R m m
