AN ARTIFICIAL SATELLITE IS MOVING IN A CIRCULAR ORBIT OF RADIUS 42250 KM.CALCULATE ITSSPEED IF ITS TAKE 24 HRS TO RESOLVE ROUND THE EARTH.

speed of the satellite
v = 2?r/T
 r is the radius of the circular path travelled by the satellite = 42250 km
 T is the time period = 24 hrs.
v = (2 X 3.14 X 42250) / 24 
   = 265330 / 24
  = 11.05km/s.
