In an elastic collision between two bodies of mass m1 and m2, with m2 initially at rest, mass 1 moves off at angle q relative to the direction of its initial velocity and mass 2 at angle f. An exam paper shows the equations below: m1v1i 0 = m1v1f cosq + m2v2f sinf = m1v1f sinq + m2v2f cosf What error(s) has the student made?

a. In the first equation, m2v2f sinf should be m2v2f cosf. b. In the second equation, m2v2f cosf should be m2v2f sinf. 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.
