The time of one revolution and its centripetal acceleration are 1.05 × 10⁴ s and 3.7 m/s². Step-by-step explanation The time taken by the satellite to complete one revolution is given by the formula: T = (2πr)/v → (equation 1). On applying Newton's second law, we getDetermining the orbital speed and orbital period of a satellite is much easier for circular orbits, so we make that assumption in the derivation that follows.
