Answer #1
angular velocity = 2pi radians/24 hours
= (pi/12) radians/hour or 15º per hour

circumference = 2pi(3960) miles

so linear speed = 2pi(3960)/24 km/h
= 660pi km/h

    The radius of the earth is a little less than 4000 miles. Using that number, how much faster is the surface moving from west to east at the equator than it would be moving if the earth were not rotating (in mph)? Consider, as in class, that air moving with the surface at the equator is warmed by the sun, rises and starts to move north. If it continues to move from west to east at the same speed that...
