Algebra.Com's Answer #816166 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! An airplane is moving at 350 km/hr. If a bomb is dropped from the airplane at 1.5 km, (a) with what velocity does the bomb strike the earth? (b) what is the bomb's range? \n" ); document.write( "----------------- \n" ); document.write( "Neglecting air resistance, the bomb's horizontal speed is constant at 350 kph. \n" ); document.write( "You didn't spec what to use for Earth's gravity, so I'll use 10 m/sec/sec. \n" ); document.write( "--- \n" ); document.write( "s = at^2/2 \n" ); document.write( "1500 = 10t^2/2 \n" ); document.write( "t^2 = 300 \n" ); document.write( " \n" ); document.write( "---- \n" ); document.write( "Vertical component \n" ); document.write( "--- \n" ); document.write( "v = at = 100sqrt(3) m/sec \n" ); document.write( "Speed at impact is the hypotenuse of the 2 components \n" ); document.write( "Vertical: 100sqrt(3) \n" ); document.write( "Horizontal: 350000/3600 m/sec = 875/9 m/sec \n" ); document.write( "---> \n" ); document.write( "That's the speed at impact. \n" ); document.write( "Did you want the velocity? \n" ); document.write( "-------------- \n" ); document.write( "IDK what \"range of the bomb\" means.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
