Use Hooke's Law to determine the work done by the variable force in the spring problem. A force of 450 newtons stretches a spring 30 centimeters. How much work is done in stretching the spring from 30 centimeters to 60 centimeters?

The work done is 202.50Nm

Step-by-step explanation:

Given

Required

The work done

First, we calculate the spring constant (k)

So:

The work done using Hooke's law is:

This gives:

Rewrite as:

Integrate

This gives:

Convert to Nm

they are simplified
