Question

The masses mi are located at the points pi. find the moments mx and my and the center of mass of the system. m1 = 2, m2 = 5, m3 = 3; p1(2, −5), p2(−3, 1), p3(3, 5) mx = my = (x, y) =

Answer 1

Most graphing calculators will do weighted averages pretty easily. It is mostly a matter of data entry.

mx = -2
my = 10
(x, y) = (mx, my)/10 = (-0.2, 1)
