Find the Center of Mass of the System Comprising Masses $m _ { k }$

question 3

Short Answer

Find the center of mass of the system comprising masses $m _ { k }$ located at the points $P _ { k }$ in a coordinate plane. Assume that mass is measured in grams and distance is measured in centimeters.
$$m _ { 1 } = 2 , \quad m _ { 2 } = 3 , \quad m _ { 3 } = 5$$
$$P _ { 1 } ( - 5 , - 1 ) , \quad P _ { 2 } ( - 4 , - 2 ) , \quad P _ { 3 } ( 4 , - 2 )$$
