# 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. - Physics

Sum

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.

#### Solution

Force exerted by the body builder against the bullworker = 150 N
Compression in the bullworker, x = 20 cm = 0.2 m

∴ Total force exerted, f = kx = 150
Here, k is the spring constant of the spring in the bullworker.

$\therefore k = \frac{150}{0 . 2} = \frac{1500}{2} = 750 \text{ N } /\text{ m }$

Hence, the spring constant of the spring in the bullworker is 750 N/m.
