In an Elastic Collision Between Two Bodies of Mass M₁ $\theta$

question 70

Multiple Choice

In an elastic collision between two bodies of mass m₁ and m₂,with m₂ initially at rest,mass 1 moves off at angle $\theta$ relative to the direction of its initial velocity and mass 2 at angle $\phi$ .An exam paper shows the equations below: m₁v_1i
0
= m₁v_1f cos $\theta$ + m₂v_2f sin $\phi$
= m₁v_1f sin $\theta$ + m₂v_2f cos $\phi$
What error(s) has the student made?

• A)In the first equation,m₂v_2f sin\(\phi\) should be m₂v_2f cos\(\phi\).
• B)In the second equation,m₂v_2f cos\(\phi\) should be m₂v_2f sin\(\phi\).
• C)In the second equation,the plus sign between the terms on the right should be a minus sign.
• D)All of the errors listed above.
• E)Only errors (a)and (b)above.
