Problem

When a

0.50\,\text{kg}

mass is hung at rest from spring A, the spring stretches

1.2\,\text{cm}

. The same mass stretches spring B by

1.8\,\text{cm}

. What is the ratio

k_A/k_B

of the springs’ stiffness constants? a)

\displaystyle 1.0

\displaystyle 2.4

\displaystyle 1.5

\displaystyle 0.67
