La testele cu rachete balistice efectuate in luna octombrie 2016 de China, toate lansarile de la o distanta de 12500 km si-au atins tinta, acesta fiind un cerc cu raza mai mica de 1 km.
Cat de mare ar fi raza cercului de tinta in cazul unui elev chinez care ar arunca o biluta metalica foarte mica de la distanta de 25 m folosind aceeasi precizie de aruncare precum cea de la testele cu rachete balistice? |

Precizia inseamna relatia dintre raza cercului de tinta si distanta de tinta. Precizia fiind aceeasi, si notand cu x raza cercului mic, avem ca x / 25 m = 1 km / 12500 km, adica:
x = 25 m * 1km / 12500 km = 0.002 m = 2 mm. |
