Homework Help: Physics Urgent please help

Posted by saru on Thursday, October 17, 2013 at 2:49pm.

A man of mass 70 kg is in free fall in the air. He reaches a terminal speed of about v_term = 54 m/s. (Note that v_term >> v_crit and we are in the pressure dominated regime where F_fric is directly propotional to v^2 ; we have g = 9.8 m/s )

What is the force (in N) due to air-drag on the man?
