Answer:
<u><em>As the penny falls 320 meters, its vertical velocity increases at the rate of 9.8 m/s each second. Use the following equation to determine its speed when it hits the ground. </em></u>
<u><em>
</em></u>
<u><em>vf^2 = vi^2 + 2 * a * d, vi = 0 </em></u>
<u><em>vf^2 = 2 * 9.8 * 320 </em></u>
<u><em>vf = √6272 </em></u>
<u><em>
</em></u>
<u><em>This is approximately 79 m/s. I hope this helps you to understand how to solve this type of problem.</em></u>
