A limb, which is 1m long, moves through an angle of 30 degrees in 0.5 seconds.

a) What is the average angular velocity of:
i) Its end?
ii) A point 30 cm from the axis of rotation?

b) What is the linear velocity of:
i) Its end?
ii) A point 30 cm from the axis of rotation?

a) convert 30 degrees to radians and divide that by 0.5 s to gegt the the angular velocity, w. It will not depend upon the position on the limb

b) For the linear velocity, multiply w by the distance from the axis of rotation.
