A person who weighs 670 N steps onto a spring scale in the bath- room, and the spring compresses by 0.79 cm. (a) What is the spring con- stant

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
