A satellite of mass 200 kg is orbiting around the Earth with constant speed, in a circular orbit. The centripetal acceleration is am = 0:6 m/s2 . We need to make a correction to its orbit so we fi re its boosts. The fi rst boost creates an instant force F1 = 40 N tangential to the orbit and the second creates an instant force F2 = 80 N away from the center. What is the total acceleration at that instant?
