Calculate tangental velocity

Apr 25, 2011 1 Replies

Can anyone please tell me how to properly apply the formula for tangental velocity when one knows the radius in meters and the frequency of rotation in Hertz.



In this case, the figures are 740 metres and 4.05MHz.



I looked online but my math is shakey.



Thank you,

Hello Mark,

It's the circumference multiplied with the frequency of rotation.

v = 2*pi*R*f

v=2*pi*740m*4.05e6/s

v = 1.883e10m/s v = 18,830,706km/s

It would be about 50 times the speed of light which is 300,000km/s. I can tell you that this is an impossible speed in this universe.

Best regards, Helmut
