Hooke's Law States That the Force F Required to Compress

Multiple Choice

Hooke's Law states that the force F required to compress or stretch a spring (within its elastic limits) is proportional to the distance d that the spring is compressed or stretched From its original length. That is, Fk= d, where k is the measure of the stiffness of the Spring and is called the spring constant. The table below shows the elongation d in Centimeters of a spring when a force of F kilograms is applied. $\begin{array} { | c | c | } \hline \text { Force, } \boldsymbol { F } & \text { Elongation, } \boldsymbol { d } \\\hline 20 & 3.5 \\\hline 40 & 6.3 \\\hline 60 & 10.0 \\\hline 80 & 13.3 \\\hline 100 & 16.5 \\\hline\end{array}$

A) F =12.098d
B) Fd= 3.024
C) F = 6.049d
D) Fd= 4.537
E) F = 7.561d
