Hooke's law:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{-}}{\mathbf{k}}{\mathbf{x}}}$

**(a) **

The two springs have the same extension, x.

F_{1} = -k_{1}x

F_{2} = -k_{2}x

F = -k_{eq}x

a) Two springs with spring constants k_{1} and k_{2} are connected in parallel. What is the effective spring constant keff? In other words, if the mass is displaced by x, find the k_{eff} for which the force equals F= -(k_{eff})x.
