I have a physics question and i cant figure out how to start it?

Question

The balance wheel of a watch oscillates with a rotaional amplitude of Pie radians and a period of 0.500s. Find the max rotational speed of the wheel....

How do i do this?

Answer 1

Max speed = wA, where A is the rotational amplitude and w is equal to 2(pi)divided by the period. So w equals 2(pi) divided by 0.500, and A is equal to pi. So max speed equals (2*pi*pi) / 0.500. Max speed equals, 39.48 rad/s
