A satellite of mass 230 kg is placed into Earth orbit at a heightof 850 km above the surface.
(a) Assuming a circular orbit, how long does the satellite take tocomplete one orbit?
1Your answer is correct. h
(b) What is the satellite's speed?
2Your answer is correct. m/s
(c) Starting from the satellite on the Earth's surface, what is theminimum energy input necessary to place this satellite in orbit?Ignore air resistance but include the effect of the planet's dailyrotation.
3Your answer is incorrect.
The satellite has some initial kinetic energy on the surface of theEarth because of the Earth's rotation. What is the total energy ofthe satellite when it is orbit? J
