1. Abu yana tafiya a daidai mita 10/s. Lissafa saurin layi na abu.
An sani :
Nauyi (m) = 1 kg
Gudun (v) = 10 m/s
Ana so: linear momentum (p)
Magani:
Tsarin motsi na layi:
p = mv
p = saurin layi, m = taro, v = gudu
Motsin layi:
p = mv = (1)(10) = 10 kg m/s 2
[irp]
2. Toshe mai nauyin kilogiram 2 da toshe mai nauyin kilogiram 4 suna motsawa a daidai mita 20/s. Menene saurin layi na toshe.
An sani:
Nauyin tubalin A (mA ) = 2 kg
Nauyin tubalin B (m B ) = 4 kg
Gudun toshe A (v A ) = 20 m/s
Gudun toshe B (v B ) = 20 m/s
Ana so: Motsin layi na toshe A (p A ) da kuma motsin layi na toshe B (p B )
Magani:
Motsin layi na toshe A :
p A = m A v A = (2) (20) = 40 kg m/s
Motsin layi na toshe B :
p B = m B v B = (4)(20) = 80 kg m/s
[irp]
3. Toshe mai nauyin kilogiram 2 yana motsawa a mitoci 2/s kuma toshe mai nauyin kilogiram 2 yana motsawa a mitoci 4/s. Kayyade saurin layi na toshe.
An sani:
Nauyin tubalin A (mA ) = 2 kg
Nauyin tubalin B (m B ) = 2 kg
Gudun toshe A (v A ) = 2 m/s
Gudun toshe B (v B ) = 4 m/s
Ana so: motsi na layi na tubalan
Magani:
Motsin layi na toshe A :
p A = m A v A = (2) (2) = 4 kg m/s
Motsin layi na toshe B:
p B = m B v B = (2)(4) = 8 kg m/s
[irp]
4. Abu mai nauyin kilogiram 5 a hutawa. Menene saurin layi na motsi.
An sani:
Nauyi (m) = 5 kg
Saurin abu (v) = 0
Ana so : ƙarfin layi (p)
Magani:
p = mv = (5)(0) = 0
