A wheel having moment of inertia 2 kg m^2 about its axis, rotates at 50 rpm about this axis. Find the torque that can stop the wheel in one minute.

Explanation

To solve the problem of finding the torque required to stop a wheel with a moment of inertia of 2 kg m² rotating at 50 rpm in one minute, we can follow these steps:

### Step-by-Step Solution:

1. **Convert Angular Velocity from RPM to Radians per Second:**
- The initial angular velocity \( \omega_0 \) in revolutions per minute (rpm) is given as 50 rpm.
- To convert this to radians per second, we use the conversion factor \( 2\pi \) radians per revolution and \( \frac{1}{60} \) minutes per second:
\[
