You can put this solution on YOUR website!
When an object's velocity changes, it \"accelerates\". Acceleration \"a\" shows the \"change\" in \"velocity\" in a \"unit\"\"+time\". \r
\n" ); document.write( "\n" ); document.write( "Velocity is measured in meters per second, \"mil%2Fh\",\"ft%2Fs\" in your case; so, acceleration is measured in \"%28mil%2Fh%29%2Fh\", or \"mil%2Fh%5E2\" \"ft%2Fs%5E2\" in your case, which can be both positive and negative.\r
\n" ); document.write( "\n" ); document.write( "\"a=%28v%5B1%5D-v%5B0%5D%29%2F%28t%5B1%5D-t%5B2%5D%29\"\r
\n" ); document.write( "\n" ); document.write( "a car that \"accelerates\" from \"rest\" (means \"v%5B0%5D=0\" at \"v%5B1%5D=9.0ft%2Fs\" for \"t%5B0%5D=0\" and\"t%5B1%5D=8.0s\"\r
