A satellite moves in orbit about the Earth at a height of 9500 km above Earth's surface. Find a) the velocity of the satellite; b) it's period of rotation; c) the magnitude of the Earth's gravitational force on the satellite if it's mass is 2500 kg; d) if the satellite's velocity is increased by 20% at what height must it now orbit the Earth?
Explain D step by step please.
