SUMMARY
The speed of a satellite in a stable circular orbit at a height of 3600 km can be calculated using the formula v² = GmE/(RE + h), where G is the gravitational constant (6.67 x 10^-11 Nm²/kg²), mE is the mass of the Earth (5.98 x 10²⁴ kg), RE is the radius of the Earth (6.38 x 10⁶ m), and h is the height of the satellite (3.6 x 10⁶ m). By substituting these values into the equation, one can derive the orbital speed. The gravitational force provides the necessary centripetal acceleration for the satellite's circular motion.
