Question

A satellite is in a circular orbit around the Earth at an altitude of 2.52 106 m.

(a) Find the period of the orbit. (Hint: Modify Kepler's third law:

          T2 =(4π^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

(c) Find the acceleration of the satellite. _________m/s2 toward the center of the earth
