Question

Many people assume air resistance acting on a moving object will always make the object show down. It can, however actually be responsible for making the object speed up. Consider a $$100\ kg$$ Earth satellite in a circular orbit at an altitude of $$200\ km$$. A small force of air resistance makes the satellite drop into a circular orbit with ab altitude of $$100\ km$$.
What force makes the satellite's speed increase?
