A 10.0 g object moving to the right at 19.0 cm/s makes an elastic head-on collision with a 15.0 g object moving in the opposite direction at 30.0 cm/s. Find the velocity of each object after the collision.

  • Physics -

    When the objects are moving in opposite directions
    v₁= {-2m₂•v₂₀ +(m₁-m₂)•v₁₀}/(m₁+m₂)
    v₂={ 2m₁•v₁₀ - (m₂-m₁)•v₂₀}/(m₁+m₂)
