Hi there!
We can use the following equation to relate angular velocity to linear velocity.
[tex]v = \omega r[/tex]
v = linear velocity (m/s)
ω = angular velocity (3.46 rad/sec)
r = distance from axis of rotation (.12 m)
Plug in the given values.
[tex]v = (3.46)(.12) = \boxed{.415 \frac{m}{s}}[/tex]
