Chris jumps off a bridge with a bungee cord (a heavy stretchable cord) tied around his ankle, as shown in the figure below. He falls for 15 m before the bungee cord begins to stretch. Chris’s mass is 75 kg. If we neglect air resistance and Chris drops another 43 m before coming to a stop, find the spring constant ? of the bungee cord. Ignore the mass of the cord and treat Chris as a particle.

Wave Motion

A wave motion is defined as the propagation of disturbances or transfer of energy and momentum from the state of rest or equilibrium to another point in a medium without any actual transfer of matter between them. In a simple explanation, it is the propagation of energy through a medium that is produced due to the repeated vibrations of the particles. Common things we see day to day like waves on water oscillation of a pendulum or bell, light wave, and all the subatomic particles exhibiting wavelike properties. The propagation of waves depends on the medium and their properties. The wave function is the disturbance that produces waves as a function of time. This disturbance oscillates periodically with a fixed frequency and wavelength. There are linear wave motion and non-linear wave motion based on their propagation, motion, and time period where linear wave motion is like sinusoidal waves and non-linear wave motion like a wave motion that gets interrupted in the middle of their propagation.
