Solve the next problems: a$)$ If a $350$ g mass is hung from a spring and it deforms by $23$ cm $,$ what will be the value of its spring constant? b$)$ If a mass of $95$ kg stretches a spring by $8$ cm $,$ what mass is required to stretches it by $10$ cm $?$

where:

F $-$ Force applied by the spring

$k-$ Proportionality constant

$x-$ Deformation distance
