Detailed Solution

An artificial satellite is moving in a circular orbit of the radius of

42250 km

. If it takes

24 hours

to revolve around the earth, its speed is

11065.48 km / hr

.
Given:

radius = 42250 km, time = 24 h

Formula:

Length of orbit = circumference of the orbit

= 2 πr

= 2 \times \frac{22}{7} \times 42250

= 265571.43 km

We know,

Speed = \frac{length of orbit}{time}

= \frac{265571.43}{24}

= 11065.48 km / hr
