The Earth rotates about its axis every 24 hours. The radius R of the equator is approximately 4000 miles. Find the angular (radians/second) and linear (feet/second) speed of a point on the equator. I am looking for help, not someone to give me the straight answer. Thanks!

Angular speed (ω) = 2π/(Time Period)

Now can you tell me the value of ω ??

Unit ??

anonymous · Answer

radians?

lastdaywork · Answer

Is it radian / second
or radian / hour
??

anonymous · Answer

radian/hour

So to fix that I would multiply 2(pi)/24 by 60/1, right?

I am sorry I had to..
@wolfe8 Can you help here ??

@ajax230 try converting the time to seconds first. 1 hour=60 minutes, 1 minute=60 seconds. It will be easier to do it this way but multiplying your speed with the 60/1 is not right.
