a) 2*pi*R(km)*(1000 m/km)
-------------------------
(24 h)*(3600 s/hr)
= ___ m/s
b) Multiply the m/s speed from (a) by
(3600 s/hr * 1 mile/1609 m)
It is important that you learn to do these conversions yourself.
Take the radius of the earth at the equator to be 6380 km
a. Find the speed the speed of an object at the equator due to the earth's rotation. ___m/s
b. Convert this speed to miles/hour (show your conversion factor in your written backup). __miles/hour
