Problem

Two springs are connected in series. Spring 1 has a breaking strength of

50\,\text{N}

and stiffness

k_{1} = 100\,\text{N/m}

. Spring 2 has a breaking strength of

120\,\text{N}

and stiffness

k_{2} = 300\,\text{N/m}

. What is the maximum possible extension of the combined system before either spring breaks?
