Problem

Two springs of constants

100\,\text{N\,m}^{-1}

and

200\,\text{N\,m}^{-1}

are connected in series. The combination is pulled by a force of

10\,\text{N}

. What is the total elastic potential energy stored in the two–spring system? a)

1.5\,\text{J}

0.25\,\text{J}

0.75\,\text{J}

0.50\,\text{J}
