An 80.0-kg skydiver jumps out of a balloon at an altitude of 1000 m and opens his parachute at an altitude of 200 m. 

(a) Assuming the total regarding force on the skydiver is constant at 50.0 N with the parachute closed and constant 3600 N with the parachute open, find the speed of the skydiver when he lands to the ground. 

(b) Do you think the skydiver will be injured? 

(c) At what height should the parachute be opened so that the final speed of the skydiver when he hits the ground is 5.00 m/s? 

(d) How realistic is the assumption that the total retarding force is constant? Explain. 

A skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g.
