## Question:

A {eq}0.490\ \mathrm{kg} {/eq} mass suspended from a spring oscillates with a period of {eq}1.50\ \mathrm{s} {/eq}. How much mass must be added to the object to change the period to {eq}1.90\ \mathrm{s} {/eq}?

The mass oscillates to and fro on the spring when subjected to a slight disturbance. The restoring force which produces the oscillation is calculated using Hooke's Law and is proportional to the initial displacement.

The time period of a mass suspended from a spring is given by:

{eq}\rm T = 2\pi \sqrt{\dfrac{m}{k}} {/eq}

Keeping all other factors constant, we...
