A bungee cord can stretch, but it is never compressed. When thedistance between the two ends of the cord is less than its unstretched lengthL0, the cord folds and its tension is zero. For simplicity, neglect the cord’s ownweight and inertia as well as the air drag on the ball and the cord. A bungee cord has lengthL0 = 33 m when unstretched; when it’s stretched to L > L0, thecord’s tension obeys Hooke’s law with "spring" constant 39 N/m. To test the cord’sreliability, one end is tied to a high bridge of height 94 m above the surface of a river) and the other end is tiedto a steel ball of mass75 kg. The ball is dropped off the bridge with zero initial speed.Fortunately, the cord works and the ball stops in the air a fewmeters before it hits the water — and then the cord pulls itback up.The acceleration of gravity is 9.8 m/s2 . Calculate theball’s height above the water’s surface at this lowest point of its trajectory. What is the tension of the bungee cord when the ballis at its lowest point?
