You can put this solution on YOUR website!
Each bounce results in the new height being 0.7 of the original height
\n" ); document.write( "HeightAtThirdZBounce=10.29m
\n" ); document.write( "so HeightAtSecondBound must be (10.29)/(0.7) = 14.7
\n" ); document.write( "and HeightAtFirstBound must be 14.7 / (0.7) = 21
\n" ); document.write( "finally originalHeight must be 21/(0.7) = 30m
\n" ); document.write( "Check your answer is $\"30%2A%280.7%29%2A%280.7%29%2A%280.7%29+=+10.29\"$ \n" ); document.write( "
