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/s², kukula kwa mphamvu F ndi 12 Newtons. Dziwani kukula ndi komwe zinthuzo zikuthamangira.

Zodziwika:

m₁ = 2 kg, m₂ = 4 kg, g = 10 m/s², F = 12 Newton

anafuna : a

Yankho:

ΣF = ma

F = (m₁ +m₂) ndi

12 = (2 + 4) a

12 = 6 a

a = 12 / 6

a = 2 m/s²

Kukula kwa kuthamanga kwa liwiro ndi 2 m/s², njira ya kufulumizitsa = njira ya mphamvu yonse = njira ya kumanja.

2. Misa chinthu 1 ndi 2 kg, kulemera kwa chinthu 2 ndi 4 kg, kuthamanga kwa mphamvu yokoka ndi 10 m/s², kukula kwa mphamvu F ndi 24 N. Dziwani kukula ndi komwe ikupita kuthamanga.

Zodziwika:

m₁ = 2 kg, m₂ = 4 kg, g = 10 m/s², F = 24 Newton

SE basi: kufulumizitsa (a)

Yankho:

ΣF = ma

F = (m₁ +m₂) ndi

24 = (2 + 4) a

24 = 6 a

a = 24 / 6

a = 4 m/s²

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