Use the Picture to the Right to Answer the Next $\alpha$

question 65

Multiple Choice

Use the picture to the right to answer the next question. A puck of m₁ and moving with 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 α below the x axis and m₂ moves with velocity v₂’ at an angle θ above the x axis.

-The conservation of momentum along the x direction can be written as

• A)m₁ v₁ = m₁v₁' cos \(\alpha\) + m₂v₂' cos \(\theta\)
• B)0 = m₁v₁' cos \(\alpha\) + m₂v₂' cos \(\theta\)
• C)m₁ v₁ = m₁v₁' sin \(\alpha\) + m₂v₂' sin \(\theta\)
• D)0 = m₁v₁' sin \(\alpha\) + m₂v₂' sin \(\theta\)
• E)none of the above
