Answer :
The moment of inertia of the solid disk is 402.12 kg.m^2. the mass of the disk is given as 84 kg and the radius is 3.1 meters.
The moment of inertia of a solid disk can be calculated using the formula:
I = (1/2) * m * r^2
Where I is the moment of inertia, m is the mass of the disk, and r is the radius of the disk.
Plugging these values into the formula, we have:
I = (1/2) * 84 kg * (3.1 m)^2
Calculating this, we get:
I = (1/2) * 84 kg * 9.61 m^2
I = 402.12 kg.m^2
