A Uniform 135-G Meter Stick Rotates About an Axis Perpendicular $0.473 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }$

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) $0.0394 \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }$
