this one for example:
the answer is supposed to be that you juggle the gold pieces. i talked to a physicist about this. he said, that if you stand on a scale, and weigh 78 kg, carry a ball that is 1 kg, the scale would show 79 kg (!). but then when u accelerate the ball (throw or catch it while juggling), the ball's weight on the scale will be a lot more than 1 kg. when you juggle (at least sometimes during the process), you do carry one ball in one hand, and accelerate another, meaning that your body would "weigh" more than 80 kgs.mind trap wrote: Confucius carried 3 gold-pieces each weighing 1 kg. Confucius weighs 78 kgs. He comes to a bridge that can only carry 80 kgs. How do Confucius get over in only one go with all the gold-pieces?
