1. The problem statement, all variables and given/known data All three disks are made of sheet metal of the same material, and the diameters are 1.2m ,2.4m , and3.6m . Assume that the x-axis has its origin at the left-most point of the left-most object and it points to the right. A) Determine the location of the center of mass of the system B) Repeat the calculation for three solid spheres all made of the same metal and having the same diameters as in part A. 2. Relevant equations cm=m1r1+m2r2...etc /m1+m2...etc 3. The attempt at a solution Now I know this is most likely a very simple problem but using my formulas I'm given doesn't seem to work for me, so I know I am setting up this wrong. I guess I need help with the whole concept of center of mass, just from assumption I know the center of mass will be between 2.4cm and 3.6cm and I know the diameters are all increasing by 1.2cm, however when I plug and chug my formula I realized all I'm doing is taking the average which cannot be true for this (I'm assuming). So I'm guessing I'm having trouble with the reference frames and figuring out the inertial values... I'm not looking for a handout answer but I do need to understand this concept, thanks in advance! Cheers!
