The spring mass system controller script is attached to the

SpringMassSystemController.cs$.$ Started with that and add required variables and

instructions to move the object by applying a force. This force is computed using the

following equation:

$=()$

$$ Incrementally increase the applied force to the spring$-$mass system and record the

displacement for several values. Create a plot such as shown below in Figure $4.$

Include a linear interpolation to find the slope, which corresponds to the spring

stiffness. In the example below, the spring stiffness would equal approximately $15\mathrm{.}5$

N$/$m$.$
