2013 F = ma Exam — Question 23

The following information applies to questions 23 and 24 A man with mass m jumps oﬀof a high bridge with a bungee cord attached to his ankles. The man falls through a maximum distance H at which point the bungee cord brings him to a momentary rest before he bounces back up. The bungee cord is perfectly elastic, obeying Hooke’s force law with a spring constant k, and stretches from an original length of L0 to a ﬁnal length L = L0 + h. The maximum tension in the Bungee cord is four times the weight of the man. 23. Determine the spring constant k. — Source: Question 23, 2013 F = ma Exam, © 2013 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
