A satellite is in a circular orbit around the Earth at an altitude of 3.60 106 m.

(a) Find the period of the orbit. (Hint: Modify Kepler's third law: T2 = (4?2/GMS)r^3 so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 106 m, and the mass of the Earth is 5.98 1024 kg.) ________ h

(b) Find the speed of the satellite. _______km/s
