# Damped oscillations - Finding damping coefficient

• diffusion
In summary, a damped oscillation is a type of periodic motion where the amplitude decreases over time due to external forces. The damping coefficient is calculated by measuring the amplitude over time and is affected by factors such as damping force, mass, and stiffness. It is important because it quantifies energy dissipation and is used in various applications to model and analyze damped oscillating systems.

## Homework Statement

A 50.0g hard-boiled egg moves on the end of a spring with force constant k = 25.0 N/m. It is released with an amplitude 0.300m. A damping force Fx = -bv acts on the egg. After it oscillates for 5.00s, the amplitude of the motion has decreased to 0.100m.
Calculate the magnitude of the damping coefficient b.

## The Attempt at a Solution
