Problem

Two identical springs, each of spring constant

k = 200\,\text{N/m}

, are fixed in parallel to a rigid wall and to a block. The block is pulled so that both springs are stretched equally by

0.04\,\text{m}

and then held. What is the total elastic potential energy stored in the system? (a)

0.16\,\text{J}

(b)

0.64\,\text{J}

(c)

0.32\,\text{J}

(d)

0.08\,\text{J}
