Question

A 150lb skydiver is falling head first position at terminal (constant) velocty of 200 mi/h. Find the force in pound of the air on the skydiver

Answer 1

We have the next information

W=150 lb

And the velocity is constant, the system is not accelereting.

Since the net force on the skydiver is zero, your acceleration will also be zero (Newton's 1st Law).

`F_{\text{net}}=W-A=0`

A is the force of the air in order to have a net force equal to zero,the force of the air will be 150 lb
