[SOLVED] Circular Motion
A rotating fan completes 1170 revolutions every minute. Consider the tip of a blade, at a radius of 18.0 cm. (a) Through what distance does the tip move in one revolution? What are (b) the tip's speed and (c) the magnitude of its acceleration? (d) What is the period of the motion?
I don't know exactly how to do these problems whatsoever because my professor didn't explain it too well. I know some circular motion formulas such as: a= the square root of ax squared + ay squared = (v squared/r) the square root of cos squared + sin squared = (v squared/r)= v squared/r.
I don't even know where to start with this problem or know an equation that includes distance for part (a). It would be great if anyone knew how I could start this problem and if those equations seem right for this problem.
