Question

A spring with a spring constant of 27.4 N/m is stretched 2.1 m. What force is required to cause this amount of stretch?

Answer 1

Given,

The spring constant of the spring, k=27.4 N/m

The stretch in the spring, x=2.1 m

The magnitude of the restoring force of the spring is given by,

`F=kx`

Where F is the force required to stretch the given spring 2.1 m

On substituting the known values,

`\begin{gathered} F=27.4*2.1 \\ =57.54\text{ N} \end{gathered}`

The force required to stretch the spring is 57.54 N
