Question

find the speed of rotation of the Earth if it takes 24 hours for one rotation. Take the radius of the earth at 6400 km.​

Answer 1

Answer:

Given radius of the earth is 6400 km

velocity of a point on the equator is

v=

24

2πR

km/hr (since the point covers 1 full rotation in 24 hrs)

acceleration of the equator point is

a=v
