question 112

Multiple Choice

A uniform 135-g meter stick rotates about an axis perpendicular to the stick passing through its center with an angular speed of 3.50 rad/s. What is the magnitude of the angular momentum of the stick?

• A) \(0.473 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
• B) \(0.158 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
• C) \(0.0236 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
• D) \(0.0739 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
• E) \(0.0394 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
