A planet rotates through one complete revolution every 28 hours. Since the axis of rotation is perpendicular to the equator, you can think of a person standing on the equator as standing on the edge of a disc that is rotating through one complete revolution every 28 hours. Find the angular velocity of a person standing on the equator.

Question

rhystic · Answer

so one full rotation is how many pi radians? a semi circle is pi radians so a full ends up being 2pi radians. angular velocity is defined as teh change in theta / change in time in this case the change in theta is 0 -> 2pi and the change in time is 0 - > 28 hours so you hae 2pi/28 or pi/14 radians per hour if you need the answer in radians per second you need to divide pi /14 by 60s/min*60min/hr so pi/(14*3600)

oooh ok! i kept getting pie/14 and leaving it that way but it was wrong. I didnt think to convert it.
