1. Chinhu chinofamba ne10 m/s. Verengai mutsetse wekufamba kwechinhu chacho.
Zvinozivikanwa :
Huremu (m) = 1 kg
Kumhanya (v) = 10 m/s
Zvinodiwa: linear momentum (p)
Solution:
Fomura yemutsara wemutsara:
p = mv
p = kumhanya kwakatwasuka, m = uremu, v = kumhanya
Mwero wemutsara:
p = mv = (1)(10) = 10 kg m/s 2

2. Chivharo che2-kg nebhuroko re4-kg zvinofamba pa20 m/s. Chii chinonzi linear momentum yemabhuroko?
Zvinozivikanwa:
Huremu hwebhuroko A (m A ) = 2 kg
Huremu hwebhuroko B (m B ) = 4 kg
Kumhanya kwebhuroko A (v A ) = 20 m/s
Kumhanya kwebhuroko B (v B ) = 20 m/s
Zvinodiwa: Linear momentum yeblock A (p A ) uye linear momentum yeblock B (p B )
Solution:
Mwero wemutsara webhokisi A :
p A = m A v A = (2) (20) = 40 kg m/s
Mwero wemutsara webhokisi B :
p B = m B v B = (4)(20) = 80 kg m/s

3. Bhokisi re2-kg rinofamba ne 2 m/s uye bhokisi re2-kg rinofamba ne 4 m/s. Sarudza kuti mabhokisi acho akamira sei.
Zvinozivikanwa:
Huremu hwebhuroko A (m A ) = 2 kg
Huremu hwebhuroko B (m B ) = 2 kg
Kumhanya kwebhuroko A (v A ) = 2 m/s
Kumhanya kwebhuroko B (v B ) = 4 m/s
Zvinodiwa: mwero wezvidhinha
Solution:
Mwero wemutsara webhokisi A :
p A = m A v A = (2) (2) = 4 kg m/s
Mwero wemutsara webhokisi B:
p B = m B v B = (2)(4) = 8 kg m/s

4. Chinhu chinorema 5 kg chakazorora. Chii chinonzi linear momentum ye momentum?
Zvinozivikanwa:
Huremu (m) = 5 kg
Kumhanya kwechinhu (v) = 0
Zvinodiwa : musimboti wakatarwa (p)
Solution:
p = mv = (5)(0) = 0
