Answer:
287.19 kg.m²
Explanation:
Given that :
The mass M of the horizontal platform = 111 kg
The radius R of the uniform disk = 1.67 m
mass of the person standing = 64.7 kg
distance of the person standing = 1.15 m
mass of the dog = 25.7 kg
distance of the dog = 1.35 m
Considering the moment of inertia of the object in the system; the net moment of the inertia can be expressed as:
=
=
= 287.19 kg.m²
