Early skeptics of the idea of a rotating Earth said that the fast spin of Earth would throw people at the equator into space. The radius of the Earth is about 6.38 x 103 km. Show why this objection is wrong by calculating

a) The speed of a 97 kg person at the equator.

Respuesta :

Answer:

463.966692822 m/s

Explanation:

Time taken for the Earth to complete one cycle = 24 hours

r = Radius of Earth = [tex]6.38\times 10^3\ km[/tex]

The distance the Earth will rotate is the circumference of the equator

Speed of the rotation of the Earth

[tex]v=\dfrac{Distance}{Time}\\\Rightarrow v=\dfrac{2\pi 6.38\times 10^3\times 10^3}{24\times 60\times 60}\\\Rightarrow v=463.966692822\ m/s[/tex]

The velocity of the Earth is 463.966692822 m/s.

Any object irrespective of mass is rotating along with the Earth at 463.966692822 m/s.

Everything that exists on Earth is in perpetual motion as the Earth has been spinning since its formation. Gravity is also pulling objects down. So, things aren't thrown off.
