I'm assuming the acceleration units are $\"km%2Fhr%5E2\"$ .
\n" ); document.write( "Convert 20 seconds to hours,
\n" ); document.write( " $\"t=20%2F3600=2%2F360=1%2F180\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"v%5BF%5D=v%5BI%5D%2Bat\"$
\n" ); document.write( " $\"v%5BF%5D=40%2B%283%29%281%2F180%29\"$
\n" ); document.write( " $\"v%5BF%5D=7200%2F180%2B3%2F180\"$
\n" ); document.write( " $\"v%5BF%5D=7203%2F180\"$
\n" ); document.write( " $\"v%5BF%5D=2401%2F60\"$ $\"kph\"$
\n" ); document.write( " \n" ); document.write( "
