Kubonderana kweInelastic muchikamu chimwe chete - matambudziko nemhinduro

1. Bara remagiramu makumi matatu richifamba ne30 m/s rinoroverana nebara re1 kg rakamira. Sarudza kumhanya kwebara kana bara nebara zvikabatana pamwe chete nekuda kwe kudhumhana.

Zvinozivikanwa:

Misa yebara (m₁) = magiramu mazana mashanu = 0.03 kg

Misa yebhuroko (m₂) = 1 kg

Kumhanya kwekutanga kwebara (v₁) = 30 m/s

kumhanya kwekutanga kweblock (v₂) = 0 (vhara pakuzorora)

Wanted : kumhanya kwebara neblock mushure mekubonderana (v')

Solution:

m₁ v₁ +m₂ v₂ = (m₁ +m₂) v'

(0.03)(30) + (1)(0) = (0.03 + 1) v'

0.9 + 0 = 1.03 v'

0.9 = 1,03 v'

v' = 0.9 / 1,03

v' = 0.87 m/s

2. Bhora rebhiriyadhi A rine huremu hwe2 kg richifamba nekumhanya v_A = 6 ms^-1 inoroverana zvakananga nebhora B rine huremu hwakaenzana. Kana kuroverana kwacho kusina kusimba zvakakwana, kumhanya kwemabhora maviri mushure mekuroverana ndekupi.

Zvinozivikanwa:

Huremu A (m)_A) = 2 kg

Huremu B (m)_B) = 2 kg

Kumhanya kwekutanga kwebhora A (v_A) = -6 m/s

Kumhanya kwekutanga kwebhora B (v_B) = 4 m/s

Zviratidzo zve "plus" ne "minus" zvinoratidza kuti zvinhu zviri kufamba nenzira yakasiyana.

Wanted: kumhanya kwemabhora maviri mushure mekuroverana. (v')

Solution:

m_A v_A +m_B v_B = (m_A' + m_B) v'

(2)(-6) + (2)(4) = (2 + 2) v'

-12 + 8 = 4 v'

-4 = 4 v'

v' = -4 / 4

v' = -1 m/s

3. m₁ = 3 kg uye m₂ = 4 kg vanoswederana munzira yakasiyana nekumhanya kwe v₁ = 10 m/s uye v₂ = 12 m/s. Kana kuroverana kwacho kusina kunyatsosimba, mabhora maviri aya anomhanya zvakadii mushure mekuroverana?

Zvinozivikanwa:

Misa Chinhu 1 (m₁) = 3 kg

Misa Chinhu 2 (m₂) = 4 kg

Kumhanya kwechinhu 1 (v₁) = -10 m/s

Kumhanya kwechinhu 2 (v₂) = 12 m/s

Wanted : kumhanya mushure mekubonderana (v')

Solution:

m₁ v₁ +m₂ v₂ = (m₁' + m₂) v'

(3)(-10) + (4)(12) = (3 + 4) v'

-30 + 48 = 7 v'

18 = 7 v'

v' = 18 / 7

v' = 2.6 m/s
