Kugundana kwa inelastic mu gawo limodzi - mavuto ndi mayankho

1. Chipolopolo cha magalamu 30 chomwe chikuyenda pa liwiro la 30 m/s chagundana ndi chipika cha 1-kg pamene chapumula. Dziwani liwiro la chipikacho ngati chipolopolocho ndi chipikacho zalumikizana pamodzi chifukwa cha kugundanako.

Zodziwika:

Kulemera kwa chipolopolo (m ₁ ) = magalamu 30 = 0.03 kg

Kulemera kwa chipika (m2 ₎ = 1 kg

Liwiro loyamba la chipolopolo ( v ₁ ) = 30 m/s

liwiro loyambirira la chipika (v ₂ ) = 0 ( chipika chili pamalo opumulira )

Kufunidwa : liwiro la chipolopolo ndi chipika pambuyo pa kugundana (v')

Yankho:

m ₁ v ₁ + m ₂ v ₂ = (m ₁ + m ₂ ) 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. Mpira wa biliyadi A wolemera makilogalamu 2 ukuyenda ndi liwiro v _A = 6 ms ⁻¹ umagundana ndi mpira B wolemera wofanana. Ngati kugundana kuli kosalala bwino, kodi liwiro la mipira iwiriyo ndi lotani pambuyo pa kugundana?

Zodziwika:

Kulemera A (m _A ) = 2 kg

Kulemera B (m _B ) = 2 kg

Liwiro loyamba la mpira A (v _A ) = -6 m/s

Liwiro loyamba la mpira B (v _B ) = 4 m/s

Zizindikiro za kuphatikiza ndi kuchotsera zimasonyeza kuti zinthuzo zimayenda mosiyana.

Ankafuna : liwiro la mipira iwiriyo pambuyo pa kugundana. (v')

Yankho:

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 = makilogalamu 3 ndi m₂ = makilogalamu 4 yandikirana wina ndi mnzake mbali yosiyana ndi liwiro la v₁ = 10 m/s ndi v₂ = 12 m/s. Ngati kugundana kuli kosalala bwino, kodi liwiro la mipira iwiriyo pambuyo pa kugundana ndi lotani?

Zodziwika:

Chinthu cholemera 1 (m1 ₎ = 3 kg

Chinthu cholemera 2 (m2 ₎ = 4 kg

Liwiro la chinthu 1 (v ₁ ) = -10 m/s

Liwiro la chinthu 2 (v ₂ ) = 12 m/s

Kufunidwa : liwiro pambuyo pa kugundana (v')

Yankho:

m ₁ v ₁ + m ₂ v ₂ = (m ₁ ' + m ₂ ) v'

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

-30 + 48 = 7 v'

18 = 7 v'

v' = 18 / 7

v' = 2.6 m/s

1. Mavuto ndi mayankho a Linear Momentum
2. Mavuto ndi mayankho a mphamvu ndi kulakalaka
3. Kugundana kosalala bwino m'mavuto ndi mayankho a gawo limodzi
4. Kugundana kopanda kukhuthala bwino m'mavuto ndi mayankho a gawo limodzi
5. Mavuto ndi mayankho a inelastic collisions mu gawo limodzi
