A small satellite is orbiting around the earth at altutude = 300km
a) What is the tangential speed of the sattelite to maintain circular orbit at this altitude
b) What decrease or increase in speed is required so that the satellite would be put on an elliptical path to reach an altitude of 24.000 km?
c) How long would it take the satellite to get to higher altitude from 300km once it's speed has been changed?
