Hi

Question

What is the center of mass of the following object measured from the center of the sphere?:

a sphere of radius R and mass m2 is connected to a solid tube of mass m1 and length L

Thank you!

Answer 1

Use the standard formula:
Σmx/σm.

Measure x from the centre of the sphere,
Σmx=ms*0 + mt*(r+L)
Σm = ms+mt
Centre of gravity
=mt(r+L)/(ms+mt)
