How powerful can a javelin be?
Around 2,500 years ago, it could be profoundly powerful. In ancient Greece, Athens and Sparta used ‘peltasts’ – infantry specialised in javelin throw – during the Peloponnesian War. In ancient Rome, Julius Ceasar’s legions used javelins to conquer Gaul.
Sounds fancy for a Saturday night binge-watch.
But, how powerful can a javelin be now? On an exhausting Thursday night?
Merely 800 grams in weight, and about 2.70 metres in length. If launched at a perfect angle, ideally 36°, with the optimum power and velocity, it could attain a speed of about 100-110 kilometres per hour, and land a few tens of metres away from the thrower.
