## Question:

A spring stretches 0.150 m when a 0.300 kg mass is gently attached to it. The spring is then set up horizontally with the 0.300 kg mass resting on a frictionless table. The mass is pushed so that the spring is compressed 0.300 m from the equilibrium point, and released from rest. What is the maximum velocity of the block?

## Energy Stored by a Spring:

When a spring of constant k is acted upon by a force such that it got compressed or stretched by a distance x it tries to bring the system to equilibrium.

Then the potential energy stored by the spring is given by {eq}E_P= \frac{1}{2}kx^2 {/eq}

Given:

A spring stretches x = 0.150 m when a m = 0.300 kg mass is gently attached to it.

Let the spring constant be k.

The spring stretches due to...
