2.0\,\text{kg}

block hangs at rest from two ideal springs arranged in parallel. The spring constants are

k_1 = 100\,\text{N/m}

and

k_2 = 150\,\text{N/m}

. How far below the unstrained position do the springs stretch while supporting the block? (Use

g = 9.8\,\text{m/s}^2

.) (a)

0.20\,\text{m}

(b)

0.33\,\text{m}

(c)

0.078\,\text{m}

(d)

0.13\,\text{m}
