Two identical pucks of equal but unknown mass head straight towards each other with velocities
of 8.0 m/s and -6.0 m/s. They collide and stick together. What is their resulting velocity?

Respuesta :

indrawboy

inelastic collision

m.8 - m.6 = 2mv'

2m = 2mv'

v' = 1 m/s

Answer:

1 m/s

Explanation:

According to the Law of Conservation of Momentum, (for inelastic collisions)

  • v = m₁v₁ + m₂v₂ / m₁ + m₂
  • v = 8m - 6m / 2m
  • v = 2m/2m
  • v = 1 m/s
