Please show all calculations, formula an assumptions if possible.
When no force is applied to the brake pedal of the lightweight truck, the retainer spring AB keeps the pedal in contact with the smooth brake light switch at C. (Figure 1)
If the force on the switch is 2N, determine the unstretched length of the spring if the stiffness of the spring is k=105N/m. Express your answer to three significant figures and include the appropriate units.
