A satellite is in a circular orbit around the Earth at an altitude of 3.40 times

Question

A satellite is in a circular orbit around the Earth at an altitude of 3.40 times 106 m. Find the period of the orbit. (Hint: Modify Kepler's third law: so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 times 106 m, and the mass of the Earth is 5.98 times 1024 kg.) Find the speed of the satellite. Find the acceleration of the satellite. A dentist's drill starts from rest. After 2.60 s of constant angular acceleration it turns at a rate of 2.2 times 104 rev/min. Find the drill's angular acceleration. Determine the angle (in radians) through which the drill rotates during this period.

Explanation / Answer

a) period of the satellite
p^2 = (4?
