A car A is approaching at a speed of 10m/sec another car B moving in the opposite direction at a speed of 20m/sec distance b/w cars is 300m
\n" ); document.write( "A fly whose absolute speed is 50m/sec goes repeatedly from A to B and back, without loosing any time at any of the cars. This repeated moving back and forth stops when the two cars crash into each other. Answer the following:
\n" ); document.write( "(i) The distance traveled by the fly before the collision is _______m.
\n" ); document.write( "(ii) The number of trips made by the fly back and forth is _________\r
\n" ); document.write( "\n" ); document.write( "Car A speed = 10m/s
\n" ); document.write( "car B speed = 20 m/s\r
\n" ); document.write( "\n" ); document.write( "combined speed = 30m/s since they are approaching each other\r
\n" ); document.write( "\n" ); document.write( "distance = 300 m\r
\n" ); document.write( "\n" ); document.write( "time they crash = 300/30 = 10 seconds\r
\n" ); document.write( "\n" ); document.write( "Speed of fly = 50 m/s\r
\n" ); document.write( "\n" ); document.write( "time it flies is 10 seconds\r
\n" ); document.write( "\n" ); document.write( "so distance it travels = 50 * 10 = 500 meters\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
