Textbook Question
Chapter 1, Problem 4P
For the free-falling parachutist with linear drag, assume a first jumper is 70 kg and has a drag coefficient of 12 kg/s. If a second jumper has a drag coefficient of 15 kg/s and a mass of 80 kg, how long will it take him to reach the same velocity the first jumper reached in 9 s?
