has anyone worked out the Earths rotation in MPH?

Answer 1

Yes, it's been done.

Answer 2

Yes. A good question. The Earth is about 40000 km. around the Equator. It takes 23 hours 56 minutes to turn once. Take out your calculator and divide 40 000 km. by that time and you should get about 1667 kilometres per hour at the Equator. If you're not on the Equator, the speed is less. It's zero at the north and south poles. That's why rocket launching sites are as close as possible to the Equator. If you launch a rocket west-to-east near the Equator, the Earth's rotational speed gives you a free speed boost. America uses Cape Canaveral. Russia uses Tyuratam. The European Space Agency uses Kouru in French Guiana. Japan uses some island south of Japan.

Answer 3

Since the earth is 25000 miles around at the equator and it rotates once in 24 hours, the speed at the equator is just over 1,000 miles per hour. You can look up the exact size numbers if you wish.

Answer 4

the earth is 24,901.55 miles diameter at the equator
it takes 24 hours to spin around
we divide the numbers, and get

1037.56 MPH at the equator
no MPH at the pole, it just spins in place.
so it depends on where you are looking at on the surface.

Answer 5

There is no MPH for earth's rotation because rotation has got angular velocity. If you are mentioning some point in earth please specify the location of the point. i.e; on the surface or somewhere in the interior.

Answer 6

1038 mph

Answer 7

At the equator it is just over one thousand miles per hour.

Answer 8

it's about 300km per hour
