Find the equation of the line that seems to best fit the data. Use the model to estimate the elongation of the spring when a force of 70 kilograms is applied. Round your answer to one decimal place.
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, 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.
A) 2.3 centimeters
B) 4.6 centimeters
C) 6.9 centimeters
D) 9.2 centimeters
E) 3.5 centimeters
