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.
