A puck of mass m₁ and initial velocity v₁ collides elastically with a second puck of mass m₂, which is initially at rest. After the collision, m₁ moves with velocity v₁' at an angle below the x axis) and m₂ moves with velocity v₂' at an angle above the x axis). Which of the following statements is true? A) Momentum is conserved in the x direction. B) Momentum is conserved in the y direction. C) The total momentum before equals the total momentum after the collision. D) The kinetic energies are conserved. E) All of the above statements are true.
