Question

Tangential Speed is 2.2m/s
Radius is 0.101m.

Find Angular Speed

Ideas: Tangential Speed = radius * angular speed.

What I don't know is the unit of measurements for the variables in the formula above.

Answer 1

I think Tangential speed is in radians/second so
2.2m/s * 1rad/0.101m = 21.7822rad/s

So I plugged it into my formula:
21.7822rad/s = 0.101m * angular speed.

I assume that these units cancel out somehow, which I'm fuzzy on.

I got angular speed = 215.665 rad/s
