1. Into ihamba ngesivinini esingaguquki esingu-10 m/s. Bala umfutho oqondile wento.
Kwaziwa :
Isisindo (m) = 1 kg
Ijubane (v) = 10 m/s
Okufunwayo: umfutho oqondile (p)
Isixazululo:
Ifomula yomfutho oqondile:
p = mv
p = umfutho oqondile, m = isisindo, v = ijubane
Umfutho oqondile:
p = mv = (1)(10) = 10 kg m/s 2

2. Ibhulokhi engu-2 kg kanye nebhulokhi engu-4 kg lihamba ngesivinini esingaguquki esingu-20 m/s. Iyini ijubane eliqondile lamabhulokhi.
Kwaziwa:
Isisindo sebhulokhi A (m A ) = 2 kg
Isisindo sebhulokhi B (m B ) = 4 kg
Ijubane lebhulokhi A (v A ) = 20 m/s
Ijubane lebhulokhi B (v B ) = 20 m/s
Okufunwayo: Umfutho oqondile webhulokhi A (p A ) kanye nomfutho oqondile webhulokhi B (p B )
Isixazululo:
Umfutho oqondile webhulokhi A :
p A = m A v A = (2)(20) = 40 kg m/s
Umfutho oqondile webhulokhi B :
p B = m B v B = (4)(20) = 80 kg m/s
[irp]
3. Ibhulokhi elingamakhilogremu angu-2 lihamba ngesivinini esingaguquki esingu-2 m/s kanye nebhulokhi elingamakhilogremu angu-2 lihamba ngesivinini esingaguquki esingu-4 m/s. Thola umfutho oqondile wamabhulokhi.
Kwaziwa:
Isisindo sebhulokhi A (m A ) = 2 kg
Isisindo sebhulokhi B (m B ) = 2 kg
Ijubane lebhulokhi A (v A ) = 2 m/s
Ijubane lebhulokhi B (v B ) = 4 m/s
Okufunwayo: umfutho oqondile wamabhulokhi
Isixazululo:
Umfutho oqondile webhulokhi A :
p A = m A v A = (2)(2) = 4 kg m/s
Umfutho oqondile webhulokhi B:
p B = m B v B = (2)(4) = 8 kg m/s
[irp]
4. Into engamakhilogremu angu-5 iphumule. Iyini ijubane eliqondile lejubane.
Kwaziwa:
Isisindo (m) = 5 kg
Ijubane lento (v) = 0
Okufunwayo : umfutho oqondile (p)
Isixazululo:
p = mv = (5)(0) = 0
