Question

A metal rod of length $ L = 0.8 \, \text{m} $ is rotating about its center with an angular velocity $ \omega = 10 \, \text{rad/s} $. What is the linear velocity of a point on the rod at a distance $ r = 0.4 \, \text{m} $ from the center?

• A. \( 4 \, \text{m/s} \)
• B. \( 8 \, \text{m/s} \)
• C. \( 2 \, \text{m/s} \)
• D. \( 6 \, \text{m/s} \)

Hint:

Remember: Linear velocity is directly proportional to both the radius and the angular velocity.
