Ned the skydiver weighs 600 N and is falling at terminal speed. That is, he has sped up until air resistance has built up so much that he has reached a final constant speed. How much work does Ned do on the air as he falls through 200 m at this terminal speed?

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
