The royal gorge bridge over the arkansas river is 393 m above the river. a bungee jumper of mass 150 kg has an elastic cord of length 78 m attached to her feet. assume the cord acts like a spring of force constant k. the jumper leaps, barely touches the water, and after numerous ups and downs comes to rest at a height h above the water. the acceleration of gravity is 9.81 m/s². find h. answer in units of m.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
