Hello! I hope someone could help me to solve mu doubt, I am very confused and I don't find answers in internet. My question is about pendulums. I know the angular frecuency of a pendulum is give by the equation w= sqrt(g/L). But also i know the angular velocity (also named with "omega") can be found from v=w.r . My question is, those w's have the same measure? or they differ?
This question arose from the following exercise:
A simple pendulum has a SHM, doing a maximum angle regarding to the vertical of 5°. Its period is 2.21s.
a) What is its lenght?
b) What is its maximum velocity?
c)What is its maximum angular velocity?
The book solution is this:

As you can see, the "w" is reckoned using v=w.r , but if I reckon the "w" with w= sqrt(g/L), the anwer is different and i don't know why.
Thanks in advance for you help
