Given,
The extension of the spring due to the attached mass, x=1.24 m
The spring constant, k=330 N/m
The weight of a mass m is given by,
[tex]F=mg[/tex]Where g is the acceleration due to gravity,
The magnitude of the restoring force of a spring is given by,
[tex]\begin{gathered} F=kx \\ \Rightarrow mg=kx \end{gathered}[/tex]Therefore,
[tex]m=\frac{kx}{g}[/tex]On substituting the known values,
[tex]\begin{gathered} m=\frac{330\times1.24}{9.8} \\ =41.76\text{ kg} \end{gathered}[/tex]Thus the mass of the weight is 41.76 kg
