A Puck of Mass M₁ and Initial Velocity V₁ Collides

question 51

Multiple Choice

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.
