A weight of 12. 0 n hangs motionless from a spring, with a spring constant of 10. 0 n/m. How far is the spring stretched from it
muminat

The extension of this spring from its original length is equal to 1.2 meter.

<u>Given the following data:</u>

  • Weight = 12 Newton
  • Spring constant = 10 N/m

To calculate the extension of this spring from its original length:

<h3>How to solve for extension.</h3>

Mathematically, the force acting on a spring is given by the formula:

F=ke

<u>Where:</u>

  • K is the spring constant.
  • e is the extension.

Making e the subject of formula, we have:

e=\frac{F}{k}

Substituting the given parameters into the formula, we have;

e=\frac{12}{10}

Extension, e = 1.2 meter.
