Question

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

Answer 1

The body builder exerts a force = 150 N

Compression, x = 20 cm = 0.2 m

$\therefore$ Total force exerted by the man = f = kx = 150

$\therefore$ $k=\frac{150}{0.2}=\frac{1500}{2}=750N/m$
