Object B has a mass of 10 kg. Object B collides with a wall and bounces off. If the momentum of object B after the collision is 18 kg m/s, what is its velocity?

Respuesta :

  • Mass=10kg
  • Momentum=18kgm/s

[tex]\\ \sf\longmapsto Momentum=Mass\times Velocity[/tex]

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

[tex]\\ \sf\longmapsto Velocity=\dfrac{18}{10}[/tex]

[tex]\\ \sf\longmapsto Velocity=1.8m/s[/tex]
