A torque of magnitude 400 N.m, acting on a body of mass 40 kg, Produces an angular acceleration of 20 rad/`s^(2)`. Calculate the moment of inertia and radius of gyration of the body.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Write down the given values
- Torque (τ) = 400 N·m
- Mass (m) = 40 kg
- Angular acceleration (α) = 20 rad/s²

### Step 2: Use the relationship between torque, moment of inertia, and angular acceleration
