Answer:
The value is [tex]F_{spring} = - k * x_f[/tex]
Explanation:
Generally the force exerted on the mass by the spring is mathematically represented as
[tex]F_{spring} = - k * \Delta x[/tex]
Here the negative sign shows that the force is acting in the negative x axis
k is the spring constant
and [tex]\Delta x[/tex] is the distance through which the spring moves the mass which is mathematically evaluated as
[tex]\Delta x = x_f -x_i[/tex]
=> [tex]F_{spring} = - k * [ x_f -x_i][/tex]
Given that [tex]x_i = 0 \ m[/tex]
[tex]F_{spring} = - k * x_f[/tex]
