You can put this solution on YOUR website!
The formula should be
\n" ); document.write( "\"d=4.9t%5E2%2BV%5B0%5D%2At\" where
\n" ); document.write( "\"V%5B0%5D\"= initial downwards velocity in meters per second \"%28m%2Fs%29\" ,
\n" ); document.write( "\"t\" = time in seconds \"%28s%29\" , and
\n" ); document.write( "\"d\"= distance fallen, in meters \"%28m%29\".
\n" ); document.write( "Once you have the right formula, all you need to do is plug in your known values;
\n" ); document.write( "\"V%5B0%5D=10\" and \"t=6\"
\n" ); document.write( "
\n" ); document.write( "\"d=%284.9%296%5E2%2B10%2A6=4.9%2A36%2B60=176.4%2B60=highlight%28236.4%29\"
\n" ); document.write( "
\n" ); document.write( "NOTES:
\n" ); document.write( "Maybe the formula you were given has a different symbol for the distance fallen, but it is not the number 5.
\n" ); document.write( "The \"4.9\" factor is a constant with units of \"m%2Fs%5E2\" .
\n" ); document.write( "If you were in physics class you would know that \"4.9\"\"m%2Fs%5E2\" is half of the acceleration of gravity on (or near) the surface of planet Earth.
\n" ); document.write( "
\n" );
