A 65.0 kg bungee jumper steps off abridge with a light bungee cord tied to her and to the bridge. Theunstretched length of the cord is 11.0m. She reaches the bottom of her motion 36.0 m below the bridge before bouncing back. Hermotion can be separated into an 11.0 mfree-fall and a 25.0 m section of simple harmonic oscillation.
What time interval is required for the cord to stretch by 25.0 m?
