Question

Calculate the linear velocity of a point at equator on the earth surface due to its rotation (radius = 6400 km)

Open in App

Solution

Time period ,T=24hour=246060=86400s
Radius of earth,r=6400Km=6400000m
linear velocity,v=ωr (ω-angukar velocity)
=(2π/T)r
=(2π/86400)*6400000
=465.185m/s (π=3.14)
