Misplaced Homework Thread

**Summary:**I am just trying to go through a Brilliant physics unit. I came across this axe throwing question which I don't get at all how they get the answer.

You can see the answer there.

So their explanation is;

'

*In going around the circle, the red point moves through an angle of*

θ = 360'

θ = 360

**°**or θ = 2π, and its angular velocity is simply ω = θ/TNow I actually thought that would be the answer.. Just 2πl/T, but they continue

'

*ω = θ/T*

= 2π X v(tangential)/l

= v(tangential/l'

= 2π X v(tangential)/l

= v(tangential/

I guess I am stuck on how they got from

*ω = θ/T*to

*ω = 2π X v(tangential)/l*

I can see how they simplified

*ω = 2π X v(tangential)/l to*ω = v(tangential/l'

I am just doing this Brilliant course because I find it interesting and want to learn more about how our world works. I am certainly no maths wiz.. lol. but I appreciate any help.
