Mourning is the investment within another person or object that goes away but the libido slowly returns to oneself through the process of mourninga and is reinvested in something else. So what is melancholia?

Physics, Astronomy & Cosmology / free fall

I have currently encountered a problem and I have come to seek your help. What is the largest distance a person can free fall and still survive? Also, how much physical force is the body capable of withstanding (Newtons)?
 
If you were wondering, I am doing a physics assignment on the chances of a person's survival during a free fall based on the criteria of height, velocity, and the amount of physical force a person can withstand.
