Question

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

Answer 1

Explanation:

r = 42250 km

t = 24 hours

= 11065 km h^-1

{\implies\dfrac{11065km}{1hour}}⟹

1hour

11065km

{\implies\dfrac{11065km}{60\times 60\:sec}}⟹

60×60sec

11065km

= 3.07 km sec^-1
