PLZ HELP. THANKS.
The balance wheel of a watch oscillates with an angular amplitude of rad and a period of 0.220 s.
a) Find the maximum angular speed of the wheel.
(b) Find the angular speed of the wheel when its displacement is /4 rad.
(c) Find the magnitude of the angular acceleration of the wheel when its displacement is /6 rad.
I used the equations of SHM, but it didn't work...
Post what you did. this is a straightforward question. I am more interested in your thinking than your work, but I can use either to critique.
I am sorry, actually I don't know where I can start with. The problem confuses me.
