In an elastic collision between two bodies of mass m₁ and m₂, with m₂ initially at rest, mass 1 moves off at angle θ relative to the direction of its initial velocity and mass 2 at angle φ. An exam paper shows the equations below: m₁v₁_i0 = m₁v₁_f cosθ + m₂v₂_f sinφ = m₁v₁_f sinθ + m₂v₂_f cosφ What error(s) has the student made? A) In the first equation, m₂v₂_f sinφ should be m₂v₂_f cosφ. B) In the second equation, m₂v₂_f cosφ should be m₂v₂_f sinφ. 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.
