A body builder exerts a force of 150 N against a bullworker and compresses it by 20cm. Calculate the spring constant of the spring in the bullworker.

Question

Philoid · Accepted Answer

Given –

Force applied to compress the bullworker = 150N

Compressed length = 20cm = 0.2m

We know, the force applied on a string is given by –

Where,

K = spring constant

X= displacement

Substituting the values

Hence, the spring constant is 750 N/m
