Question

As shown in the figure, a spring is kept in a stretched position with some extension by holding the masses 1 kg and 0.2 kg with a separation more than spring natural length and are released. Assuming the horizontal surface to be frictionless, the angular frequency (in SI unit) of the system is :

Accepted Answer

$\mu = \frac{m_{1}{	ext{ }m}_{2}}{{	ext{ }m}_{1} + m_{2}} = \frac{1 	imes 0.2}{1.2}$$${\mu = \frac{1}{6} }{\omega = \sqrt{\frac{k}{\mu}} = \sqrt{\frac{150}{1/6}} = 30}$$
