Answer:
Using the equation for orbital speed
orbital speed= square root of GM/r
Where
G= Gravitational Constant = 6.674x10^-11m^3/kg.s^2
M= mass of The Earth=5.972x10^24 kg
r= the combined radius of The Earth and the height of the satellite above The Earth=6378km+ 3600km= 9978km converting to meters gives (1000m=1km) 9978km*1000m/1km= 9,978,000m or 9.978x10^6m
orbital speed = square root of (6.674x10^-11*5.972x10^24/9.978x10^6= 63198m/s
