Champagne bottles are often opened by ‘firing’ the cork out of the bottle. The world record for the horizontal distance travelled by a fired cork is 53m.
The high pressure inside the bottle produces an average force of 150 N on the cork as it leaves the bottle. This force acts on the cork over a distance of 2.5 × 10^–2m.
mass of cork = 7.5 × 10^–3 kg
The cork is fired from ground level at an angle of 40° to the horizontal with a speed of 32 m s^–1
