\r\n" );
document.write( "We have uniformly decelerated movement with the initial speed of 24 m/s\r\n" );
document.write( "and the final speed of 0 m/s after 0.4 seconds\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, we can calculate the deceleration value \"a\": it is  a =  = 60 m/s^2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now we can calculate the distance to stop\r\n" );
