An artificial satellite is moving in a circular orbit of radius 42250 km. Calculate it's speed if it takes 24 hours to revolve around the earth.
Answers
Answer:
3.07 km/s power -1
Explanation:
Distance covered by the satellite in 24 hours
s=2πr
=2×3.14×42250=265464.58 km
Therefore speed of satellite,
v= distance travelled/time taken
= 265464.58/24×60×60
=3.07 km/s power -1

Answer:
Explanation:
Given :-
Radius of circular orbit, r = 42250 km
Time taken, t = 24 hours
To Find :-
Speed
Formula to be used :-
Speed = Distance/Time
Circumference = 2πr
Solution :-
Putting all the values, we get
Circumference = 2πr
⇒ Circumference = 2 × 22/7 × 42250
⇒ Circumference = 465571.4 km
Now, Speed
Speed = Distance/Time
⇒ Speed = 465571.4/24
⇒ Speed = 11065.4 km/h
We will now convert it in m/s
= 11065.4 × 5/18
= 3070.9444 m/s
Now to km/h
= 3070.9444/1000
= 3.070 km/s
Hence, the speed is 3.070 km/s.
