Question

What is the moment of inertia of a pendulum with a mass of `9 kg` that is `15 m` from the pivot?

Answer 1

The moment of inertia is `=2025kgm^2`

Explanation:

The moment of inertia is

`I=mr^2`

The mass is `m=9kg`

The distance from the pivot is `r=15m`

The moment of inertia is

`I=9*15^2=2025kgm^2`
