49. (a) If r is the radius of the orbit then the magnitude of the gravitational force acting on the satellite is given by GMm/r 2 , where M is the mass of Earth and m is the mass of the satellite. The magnitude of the acceleration of the satellite is given by v 2 /r , where v is its speed. Newton’s second law yields GMm/r 2 = mv 2 /r . Since the radius of Earth is 6.37 × 10 6 m the orbit radius is
