Question

A hollow sphere of mass 1.4 kg has a radius of 1.5 m and has a linear speed of 5.6 m/s at the edge. what is the angular momentum of the hollow sphere?

Answer 1

We will have the following:

`I=(1.4kg)(1.5m)(5.6m/s)\Rightarrow I=11.76kg\cdot m^2/s`

So, the moment of inertia of the hollow sphere is 11.76 kg*m^2/s.
