1. Inhlamvu engamagremu angu-30 ehamba ngesivinini esingama-30 m/s ishayisana nebhulokhi elingu-1 kg lapho iphumule. Thola isivinini sebhulokhi uma inhlamvu nebhulokhi kuxhumene ngenxa yokushayisana.
Kwaziwa:
Isisindo senhlamvu (m 1 ) = amagremu angu-30 = 0.03 kg
Isisindo sebhulokhi (m2 ) = 1 kg
Isivinini sokuqala senhlamvu ( v 1 ) = 30 m/s
isivinini sokuqala sebhulokhi (v 2 ) = 0 ( ibhulokhi lapho iphumule )
Okufunwayo : isivinini senhlamvu kanye nebhulokhi ngemva kokushayisana (v')
Isixazululo:
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. Ibhola lebhiliyadi A elinobunzima obungu-2 kg lihamba ngesivinini v A = 6 ms −1 lishayisana ngqo nebhola B elinobunzima obulinganayo. Uma ukushayisana kungaqini ngokuphelele, zingakanani izivinini zamabhola amabili ngemva kokushayisana.
Kwaziwa:
Isisindo A (m A ) = 2 kg
Isisindo B (m B ) = 2 kg
Isivinini sokuqala sebhola A (v A ) = -6 m/s
Isivinini sokuqala sebhola B (v B ) = 4 m/s
Izimpawu zokuhlanganisa kanye nokususa zibonisa ukuthi izinto zihamba ngendlela ehlukile.
Okufunwayo : isivinini samabhola amabili ngemva kokushayisana. (v')
Isixazululo:
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 = 3kg futhi m2 = 4kg basondelane ngendlela ephambene ngesivinini v1 = 10m/s futhi v2 = 12 m/s. Uma ukushayisana kunganambitheki ngokuphelele, zingakanani ijubane lamabhola amabili ngemva kokushayisana?
Kwaziwa:
Into enesisindo 1 (m1 ) = 3 kg
Into enesisindo 2 (m2 ) = 4 kg
Isivinini sento 1 (v 1 ) = -10 m/s
Isivinini sento 2 (v 2 ) = 12 m/s
Okufunwayo : isivinini ngemva kokushayisana (v')
Isixazululo:
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
