Question

The linear velocity of particle on equator is nearly (radius of earth is 4000 mile)

Answer 1

Earth 4000 mile radius as well as rotates as 1 revolution every 24 hours.

Circumference of the earth at equator = 2πr = 2π*4000 = 8000π miles linear speed of the point on the equator = 8000π mi/24hrs ≈ 1047 mi/hr.

You could conveniently get the complete aspiration for extending major aspects and enabled with more different aspects to the maximum.

Answer 2

Answer:formula

Linear velocity =2πnr

Explanation:

Therefore,

Lin.v= 2πr/T

=2×π×4000miles/24hrs

=1046.6miles/hrs

Approximately your answer is 1047miles per hrs
