Szia!


>Valamelyikunk nem jol szamol, szerintem gyorsabban fog jonni, mint 45 km/h.

Parametertol fugg, irj be kisebb-nagyobb tomeget, feluletet. Realis esetben kijohet termeszetesen akar repulogep-sebesseg is (mondjuk 400-600 km/ora), de lehet talalni 30-40 km/oras vegsebesseget is. Esete valogatja. De a becsapodas energiaja nem nagy (kicsi a tomeg). Mellesleg most jutott eszembe: amikor a ko leer, miert ne pattana vissza? A visszapattanas soran akar mozgasi energiaja felet is elveszitheti. Es akar tobb meterre is elugorhat az elso foldet eresi ponttol. Tud errol valaki valamit?
