Correct Answer: Option C

Explanation

To find the angular speed (\( \omega \)) of an object moving in a circle, we use the formula:

\(\omega = \frac{v}{r}\)

Given:
- Linear speed (\( v \)) = 10 m/s
- Radius (\( r \)) = 4 m
Substituting the values into the formula:

\(\omega = \frac{10 \, \text{m/s}}{4 \, \text{m}} = 2.5 \, \text{rad/s}\)
The angular speed is  \(\omega = 2.50 \, \text{rad/s}\)
