A basketball falls freely from a high altitude. Each time it touches the ground, the height of its bounce is (2/5) the height of the previous drop. If the ball falls from a height of 35 meters, what is the height of the second bounce?

<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">35 * (2/5) * (2/5)</gadget>
<output>28/5 = around 5.6</output>

<result>28/5 = around 5.6</result>
