Part A :
given
the mass of the satellite 1 is m1 = 68 kg ,
the mass of the satellite 2 is m2 = 84 kg ,
the orbital radius of satellite 1 is 7 X 107 = r1
the orbital radius of satellite 2 is 4 X 107 = r2
the orbital speed is Vo1 = 4800 m/sec
the orbital speed Vo = ( G m / r )
Vo1 / Vo2 = ( r2 / r1 )1/2
Vo2 = Vo1 ( 4 X 107 / 7 X 107 )1/2
Vo2 = 4800 X ( 4 X 107 / 7 X 107 )1/2
Vo2 = 3628.45 m/sec
