Radius of the circular orbit, \(r\) = \(42250\) \(km\)
Time taken to revolve around the earth, \(t\) = \(24\) \(h\)
Speed of a circular moving object, \(v\) = \(\frac{(2\pi r)}{t}\)
= \(\frac{\bigg[2× (\frac{22}{7})×42250 × 1000\bigg] } {(24 × 60 × 60)}\)
=\(\frac{(2×22×42250×1000) }{(7 ×24 × 60 × 60) }m s^{-1}\)
=\(3073.74\; m s ^{-1}\)
The rate at which an object covers a certain distance is commonly known as speed.
The rate at which an object changes position in a certain direction is called velocity.
