Chapter 8, Problem 26(choose chapter or problem)
An 80.0-kg skydiver jumps out of a balloon at an altitudeof 1 000 m and opens his parachute at an altitudeof 200 m. (a) Assuming the total retarding force on theskydiver is constant at 50.0 N with the parachute closedand constant at 3 600 N with the parachute open, findthe speed of the skydiver when he lands on the ground.(b) Do you think the skydiver will be injured? Explain.(c) At what height should the parachute be opened sothat the final speed of the skydiver when he hits theground is 5.00 m/s? (d) How realistic is the assumptionthat the total retarding force is constant? Explain.
