Formula used:-

Momentum =Mass×Velocity

Solution:-1

  • Mass=2kg
  • Velocity=3.5m/s

[tex]\\ \sf\longmapsto Momentum=2\times 3.5[/tex]

[tex]\\ \sf\longmapsto Momentum=7kgm/s[/tex]

Solution:-2

  • Mass=1524kg
  • Momentum=18000kgm/s

[tex]\\ \sf\longmapsto Velocity=\dfrac{Momentum}{Mass}[/tex]

[tex]\\ \sf\longmapsto Velocity=\dfrac{18000}{1524}[/tex]

[tex]\\ \sf\longmapsto Velocity=1.18m/s[/tex]

Solution:-3

  • Mass=50kg
  • Velocity=0m/s

[tex]\\ \sf\longmapsto Momentum=50\times 0[/tex]

[tex]\\ \sf\longmapsto Momentum=0kgm/s[/tex]

Solution:-4

  • Momentum=2.5kgm/s
  • Mass=0.5kg

[tex]\\ \sf\longmapsto Velocity=\dfrac{Momentum}{Mass}[/tex]

[tex]\\ \sf\longmapsto Velocity=\dfrac{2.5}{0.5}[/tex]

[tex]\\ \sf\longmapsto Velocity=5m/s[/tex]

Solution:-5

  • Mass=79000kg
  • Velocity=76m/s

[tex]\\ \sf\longmapsto Momentum=79000\times 76[/tex]

[tex]\\ \sf\longmapsto Momentum=6014000kgm/s[/tex]
