A ball falls freely from a high place, and the height of each bounce after touching the ground is (2/5) of the height of the previous drop. If the ball falls from a height of 70 meters, what is the height of the second bounce?
球从高处自由下落，每次接触地面后弹起的高度是前次下落高度的(2/5)，如果球从70米的高处落下，那么第二次弹起的高度是多少米？

<output>2/5 = around 0.4</output>

<gadget id="calculator">70 * (2/5) * (2/5)</gadget>
<output>56/5 = around 11.2</output>

<result>56/5 = around 11.2</result>
