## Question:

A vertical scale on a spring balance reads from 0 to 220 N. The scale has a length of 15.0 cm from the 0 to 220 N reading. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.45 Hz.

Ignoring the mass of the spring, what is the mass m of the fish?

## Spring-mass Oscillation:

The simple harmonic motion is nothing but the periodic motion of the spring-mass system and it is described by the frequency of oscillation and period of oscillation of the spring-mass system. The frequency of the oscillation is the function of a concentrated mass attached at the end of the spring and stiffness constant of the spring.

Given data:

• Spring force {eq}F=\rm 220 \ N {/eq}
• Length of the scale {eq}x=\rm 15 \ cm=0.15 \ m {/eq}
• Frequency of oscillation {eq}f=\rm 2.45 \...
