document.write( "In 5 seconds decelerating, the bus covered 80 meters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the bus average speed vas 80/5 = 16 m/s  during this time interval.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Since the speed was changed LINEARLY as the function of time (! uniform deceleration !),\r\n" );
document.write( "the speed of the bus before decelerating was 32 m/s.\r\n" );

document.write( "Deceleration of the bus was  32 m/s : 5 seconds =  = 6   m/s^2 = 6.4 m/s^2.\r\n" );
