Find v for each of the following:
a) the tip of the second hand of a clock, if the hand is 28 mm long
b) a point on the tread of a tire radius 18 cm, rotating 35 times per minute
c) a point on the edge of a gyroscope of radius 83 cm, rotating 680 times per minute
I'm pretty sure I'm supposed to use the formula v=rw, where w (omega) is angular speed and r is radius.
I'm not sure how to find w. Could someone please help?
