## Question:

A mass of 0.40 kg with spring constant of 40N/m. What is the magnitude of acceleration of the mass when the maximum displacement is 0.25 m?

## Hooke's Law

Hooke's Law is a relationship between the force {eq}F_s {/eq} exerted by a spring and the distance {eq}\Delta x {/eq} it has been displaced from its neutral or rest position.

{eq}\vec{F}_s=-k\Delta\vec{x} {/eq}

Note the negative sign, this indicates the force will be directed back toward the neutral position; if calculating only magnitude, disregard the negative. The spring constant {eq}k {/eq} is specific to the individual spring and may be experimentally determined.

We are given the following:

{eq}m=0.40 kg {/eq}

{eq}k=40 \frac{N}{m} {/eq}

{eq}\Delta x = 0.25 m {/eq}
