Kuyenda pamalo opingasa popanda mphamvu yokangana - kugwiritsa ntchito lamulo la Newton la mavuto oyenda ndi mayankho ake

1. Kulemera kwa chinthu 1 ndi 2 kg, kulemera kwa chinthu 2 ndi 4 kg, kufulumira kwa mphamvu yokoka ndi 10 m/s ² , kukula kwa mphamvu F ndi 12 Newtons. Dziwani kukula ndi komwe zinthuzo zikuthamangira.

Zodziwika:

m ₁ = 2 kg, m ₂ = 4 kg, g = 10 m/s ² , F = 12 Newtons

Ankafuna : a

Yankho:

Σ F = ma

F = (m ₁ + m ₂ ) a

12 = (2 + 4) a

12 = 6 a

a = 12 / 6

a = 2 m/s ²

Kukula kwa kuthamanga ndi 2 m/s ² , njira ya kuthamanga = njira ya mphamvu ya ukonde = njira yakumanja.

2. Kulemera kwa chinthu 1 ndi 2 kg, kulemera kwa chinthu 2 ndi 4 kg, kufulumira kwa mphamvu yokoka ndi 10 m/s ² , kukula kwa mphamvu F ndi 24 N. Dziwani kukula ndi komwe kumayambira kufulumira.

Zodziwika:

m ₁ = 2 kg, m ₂ = 4 kg, g = 10 m/s ² , F = 24 Newtons

Kufunidwa: kufulumizitsa (a)

Yankho:

Σ F = ma

F = (m ₁ + m ₂ ) a

24 = (2 + 4) a

24 = 6 a

a = 24 / 6

a = 4 m/s ²

Kulunjika kwa kufulumizitsa = njira ya mphamvu ya ukonde = njira ya kumanja.
