Question

An artificial satellite is moving in a circular orbit of radius 42250 kilometre . Calculate its speed if it takes 24 hours to revolve around the earth

Answer 1

Answer:

Explanation:

s = d / t

s = c f of earth / 24

s = 6378.1 /24

Answer 2

Distance covered by satellite in 24 hours =2πr

$\longrightarrow$$\large\sf{2×\frac{22}{7}×42250}$

$\therefore$$\large\sf\orange{Speed\:of\:Satellite=\frac{Distance}{Time}}$

$\longrightarrow$$\large\sf{\frac{2×22×42250}{7×24}}$

$\longrightarrow$$\large\sf{11065.48km/h}$
