b) Collisions in two dimensions

• state the principle of the conservation of momentum

• total momentum before a collision = total momentum after the collision

• state how to calculate the total initial momentum of two objects before a collision

• p₁² = p₂² + p₃²

  • (total initial momentum of mass 1 and 2)² = (total final momentum of mass 1)² + (total final momentum of mass 2)²

• state how to calculate the total momentum in the x-direction of a collision

• state how to calculate the total momentum in the y-direction of a collision

• m₁v₁ = (m₁)(v₂cosθ₁) + (m₂)(v₃cosθ₂)

• m₁v₁ = (m₁)(v₂sinθ₁) + (m₂)(v₃sinθ₂)

• n/a
