In this problem we have this two -dimensional xy plane and on top of it we have some masses.
00:14
Let's pick a different color.
00:17
So here we have m1, somewhere here we have m2, and even though it is not given like that, i'm going to call this m3.
00:33
And there are some distance in between.
00:38
So this distance is 12 centimeters.
00:44
This height is 10 centimeters and there is something over there which is totally irrelevant to our problem.
00:56
Now let us also write down the okay, let's pick a different from the right down the mass value.
01:03
So, n1 is equal to...
01:07
160 grams m2 is equal to 350 grams and this m3 guy is 200 grams and we are asked to find the x and y coordinate of the center of mass of this object okay so the center of mess is given by okay in terms of x and y coordinates separately like that okay let's indicate by capital x so we have a summation over the individual x values but we need to weigh them by the masses and we divide this guy by the total mass of these objects.
02:07
Very similarly to get the y coordinate of the center of mass.
02:14
We have the individual y values multiplied by the masses and we divide this summation by the total mass...
