Question

A 5 kg mass is attached to an end of a spring that hangs vertically. The spring has a spring constant of 50 N/m. If

the spring is displaced 5 cm from its unstretched position and then released, what is the period of oscillation of
the mass-spring system?

Answer 1

`\tt T=2\pi \sqrt{(m)/(k) }\\\\T=2\pi \sqrt{(5)/(50) }=1.96~s`
