Question:

A tractor is trying to pull a 1 tonne trailer with a spring in the connection between them. The spring has a spring constant of 0.125 MN/m. The spring stretches by 80 mm. What is the acceleration of the tractor (in {eq}\rm{m/s^2} {/eq})?

Spring force

According to Hooke's law, the spring force required to produce an expansion or compression in the length of the spring is equal to the product of the spring constant of the spring with the length of the compression or expansion produced.
