In this problem we have been given three masses and we need to figure out the center of mass of these three masses with respect to this one kilogram mass.
00:12
So the second object, this has a mass of 1 .5 kilograms and the third object here at the extreme right that has mass of 1 .1 kilograms.
00:26
Provided that the separation between 1 kg and 1 .5 kg is 0 .5 meters and the separation between this mass 2 and 3, that's 2 .25 meters.
00:41
So to figure out the center of mass, let's just consider them along the x -axis, whereby we will consider this object 1 kg to be positioned at the origin.
00:52
And here the mass 1 .5 kilogram that will have the coordinate of 0 .50 and the mass 3 will have the coordinate 0 .750.
01:05
That's the coordinate with respect to this 1 kg mass.
01:09
So we directly use the expression of determining the center of mass.
01:14
X -e -m will be equal to m1x1 plus m2x2 plus m3 divided by the total mass.

Of these three objects...
