You will need to use the formula 4.9t2 + v0t = s, where t is the time in seconds, v0 is the initial velocity, and s is the distance in meters.
\n" ); document.write( "Approximately how far will an object fall in 13 seconds (t) when thrown downward at an initial velocity of 10 meters per second (v0) from a plane?
\n" ); document.write( ".
\n" ); document.write( "Starting with the provided equation: (I think you forgot the negative sign in front of the 4.9)
\n" ); document.write( "\"+-4.9t%5E2+%2B+v0t+=+s+\"
\n" ); document.write( "Notice, it said \"thrown downward\" so Vo will be -10 meters per second.
\n" ); document.write( "Plug in the given info:
\n" ); document.write( "\"+-4.9%2813%29%5E2+%2B+%28-10%29%2813%29+=+s+\"
\n" ); document.write( "\"+-4.9%28169%29+%2B+%28-10%29%2813%29+=+s+\"
\n" ); document.write( "\"+-828.1+-+130+=+s+\"
\n" ); document.write( "\"+-958.1+=+s+\" (meters)
\n" ); document.write( ".
\n" ); document.write( "That is, it will fall 958.1 meters
\n" ); document.write( "
\n" );
