Homework Statement
All three disks are made of sheet metal of the same material, and the diameters are 1.0 m , 2.0 m , and3.0 m . Assume that the x-axis has its origin at the left-most point of the left-most object and it points to the right. Part A) Determine the location of the center of mass of the system shown
.
part B)Repeat the calculation for three solid spheres all made of the same metal and having the same diameters as in part A.
Homework Equations
m1x1+m2x2+m3x3/m1+m2+m3
The Attempt at a Solution
i have gotten the answer for the first part with some help, the answer was 3.5m. i have tried repeating the calculations i took in part A. and got 3.5m again. this is what i did;
Masses
4πr2
mass 1: 4π(0.5)2=3.14159
mass 2:4π(1)2=12.56637
mass 3: 4π(1.5)2=28.2743
center of mass of the system
3.14159(0.5)+12.56637(1)+28.2743(4.5)/3.14159+12.56637+28.2743
