Well, for me it was a bit confusing and i am very afraid that the grade thresholds might be so high  :-\ !!!

This was one of the questions that confused me somehow, anyways what were your answers to the two equations and the trolley with the greater kinetic energy.

I hated the question of the diffraction grating being rotated parallel to the beam  :( .
