Answer:
The spring constant is 84,810.13 N/m
Explanation:
Given;
applied force on the spring scale, f = 670 N
extention of the spring, x = 0.79 cm = 0.0079 m
Apply Hook's law to determine the spring constant;
f = kx
where;
f is the applied force
k is the spring constant
x is the is the extension
k = f / x
k = 670 / 0.0079
k = 84,810.13 N/m
Therefore, the spring constant is 84,810.13 N/m
