In the dangerous “sport” of bungee jumping, a daring
student jumps from a hot air balloon with a specially designed
elastic cord attached to his waist. The unstretched length of
the cord is 25.0 m, the student weighs 7.00 x 102 N, and the
balloon is 36.0 m above the surface of a river below. Calculate
the required force constant of the cord if the student is to stop
safely 4.00 m above the river.
