Question

A satellite is in a circular orbit around the Earth at a distance where the gravitational field is g = 2.0 m/s2 . (a) What is the radius of the orbit? (b) What is the period of the orbit? (c) What is the acceleration of the satellite (magnitude and direction)? (d) If the satellite were to suddenly stop and fall to Earth from that altitude, what would be the speed of impact at the surface of the Earth? (neglect air resistance) Radius of Earth = 6,380 km Mass of Earth = 6.0 x 1024 kg
