Linear velocity = v = ωr

In this example, ω = 130 rad/s and r = 0.225 m

So the linear velocity is:

v = 130 × 0.225 = 29.3 ms-1.

Note 1: ms-1 is an equivalent way of writing m/s. This comes from the index laws where the rule is `s^-1= 1/s`.

Note 2: It is common in physics to write velocity using ms-1 and the units for acceleration as ms-2.
