3 Ngā raruraru me ngā otinga mō te whārite o te wā o te korekore
1. Ko te radius o tētahi rango totoka he 8 cm te whānui, ā, ko te taumaha he 2 kg. I taua wā, ko te radius o tētahi pōro totoka he 5 cm te whānui, ā, ko te taumaha he 4 kg. Mena ka huri ngā mea e rua me te tuaka i roto i tō rāua pokapū, whakatauhia te ōwehenga o te wā o te inertia o te rango me te pōro.
Mōhiotia:
Te pūtoro o te rango totoka (r) = 8 cm = 0.08 m
Papatipu rango totoka (m) = 2 kg
Te pūtoro o te pōro totoka (r) = 5 cm = 0.05 m
Ko te taumaha o te pōro totoka (m) = 4 kg
E hiahiatia ana: Te whakataurite i te wā o te korekore o te rango me te pōro
