If you free the cork in a highly pressurized champagne bottle, the resulting launch ofthe cork will (in principle) cause the bottle to recoil. A filled champagne bottle has a mass of 1.7 kg. The cork has a mass of 7.3 g and is launched at 20 m/s. If the bottle could move freely, with what speed would it recoil? Is this a speed you are likely to notice?
