The speed of the tip of the minute hand on a town clock is 0.00112 m/s. What is the speed of the tip of the second hand of the same length? Answer in units of m/s. I don't even know where to start. We've been doing centripetal acceleration but I don't know how this even fits in to that? I was thinking I could somehow set them equal to each other because of the same length that they have - but not sure how to go about that. If anyone could please help?
