## Question:

A hand exerciser utilizes a coiled spring. A force of 85.0 N is required to compress the spring by 0.0151 m. Determine the force needed to compress the spring by 0.0503 m.

## Hooke's Law:

When a spring is stretched or compressed by an external applied force, it tends to oppose the applied force in a bid to restore itself to its equilibrium position. The magnitude of the applied force is directly proportional to the magnitude of the stretch or compression. This a consequence of Hooke's law.

Given,

• magnitude of the applied force, {eq}F = 85.0\ \rm{N} {/eq},
• magnitude of the compression, {eq}x = 0.0151\ \rm{m} {/eq},
