c) A penny sits 12 cm from the center of a record turning at 33 1/3 rpm. What is the tangential speed in m/s?


d) A mass spins with a tangential speed of 1.2 m/s on the end of a string which is 0.75m long. What is the period of the rotation in seconds?

    These problems are not hard. You need to show your work, or evidence of thought about the problem.

    Start (c) by converting rpm to radians per second

    I was not taught how to do this

    We went over this in my physics class yesturday, and I understand most of the concepts of this section of the book, but the examples we were given confuse me. I can find no connection between the numbers of tangential speed and RPM. :(
