<p>Questions 23 24
A 0. l kilogram block is attached to an initially unstretched spring of force constant k = 40 newtons per meter as shown above. The block is released from rest at time t = 0.</p>

<ol>
<li><pre><code>What is the amplitude of the resulting simple harmonic motion of the block?
</code></pre>

<p>(A) m (B) (C) (D) (E) 1m</p></li>
<li><pre><code>At what time after release will the block first return to its initial position?
</code></pre>

<p>23 - the answer is just how far the block was initially stretched.
24 - Find the period of the harmonic motion (2pi *sqrt(m/k))</p>
