Question

an artificial satellite is moving in a circular orbit of radius 42250 km calculate the speed if it takes 24 hours to revolve around the earth

Answer 1

Answer:

Step-by-step explanation:

Let the satellite moving in circular orbit of radius be 42250km

Radius of circular orbit “r”

Time taken by artificial satellite t=24hr

Distance covered by satellites s=circumstances of circular orbit

Speed of satellite “V”

=3.073km/s

Answer 2

Answer:

Approx. 11055 km/hr, or approx. 3071 m/s.

Step-by-step explanation:

Radius of the orbit is 42250km, so the circumference is:

C = 2πr = 2 * 3.14 * 42250 km = 265330 km.

The circumference is the actual distance along which the satellite would move.

Now, speed = distance / time.

So, speed = 265330/24 km/hr = 11055 km/hr.
