A 90 kg student jumps off a bridge with a 8-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 400 N/m. You can assume that the bungee cord exerts no force until it begins to stretch. How far below the bridge is the student's lowest point? How far below the bridge is the student's resting position after the oscillations have been fully damped?

A certain unstretched bungee cord is 26 m long. A 73 kg person attaches one end of the cord to himself and the other end to the top of a 782 m high bridge. He then slowly lowers himself from the bridge.What must the spring constant of the cord be so that the person is just barely touching the ground when the cord is fully stretched?

A bridge oscillates too much during high winds. The bridge is modeled as a spring with simple harmonic motion. The mass of the bridge is 5.0x106 kg and its spring constant is 4.9x10' N/m. The peak vertical displacement of the bridge is 1.0 m from its equilibrium position. In order to reduce this motion, dampers are added to the bridge with a damping coefficient of 3.13x10² kg/s. a) Derive, but do not solve, the equation of motion which describes the...
