Earth rotates in on axis that goes through both the North and South Poles. It makes one complete revolution in 24 hours. If the distance from the axis to any location on the equator is 3960 miles, find the linear speed (in miles per hour) of a location on the equator.
The Attempt at a Solution
I used the formula V=rw to find the linear velocity, and for 'r' I used 3960, and 'w' is used 2pi/24 for making one revolution per hour, so I simplified that down to pi/12 as angular velocity.
V=3960 x (pi/12 radians/hour)≈ 1036.73 miles/hour
Is this correct? It got checked in school, but I think I was off in the decimals or something. Is there something I did wrong or?
Thanks for any help!
