Please explain and solve with a clear explantion 

Example 11.3
a. Determine the drag coefficient of a 75 kg
skydiver with a projected area of 0.33 m² and
a terminal velocity of 55 m/s.
b. By how much would the skydiver need to
reduce her project area so as to double her
terminal velocity? How would she accomplish
this?
Concept: Terminal velocity for a falling object occurs
when the drag on the object equals its weight.
