Uncategorized: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Uncategorized. Understanding the underlying formula is key to arriving at the correct answer below:

Given: Frequency \( f = 120 text{ revolution/minute} \). Convert to revolutions per second: \( f = frac{120}{60} = 2 text{ rev/s} \). The angular speed is given by \( omega = 2pi f \). Substituting the frequency, \( omega = 2pi (2) = 4pi text{ rad/s} \).
