Masses Connected by a Spring

Two equal masses are connected by a spring satisfying Hooke's law. The spring is elongated a little and allowed to let go.. Let the angular frequency of oscillations be \(\omega\). Now one mass stopped. What is the square of the new frequency? Discussion: $$ \mu=\frac{m}{2}$$ $$ \omega^2=k/\mu=2k/m$$ When one block is stopped $$ \omega_1^2=k/m=\omega^2/2$$ Useful […]
