[ivanchenko]

Mate for making these. You are an absolute legend!

I also think you might have mispoke in q8 - at 09:07 you say that 'velocity is constant throughout', I think you mean 'horizontal velocity is constant throughout'.

[plamenpenchev]

Two questions are using the value of a constant which is an idiotic idea. Remembering constant values is not necessary to become a good physicist. Nevertheless, I put a thumb up because I get some ideas for my students (Molecular Spectroscopy)

i think the explanation for question 6 is correct, but you may have circled the wrong answer ;)

Question 6 your explanation is correct but the answer is A not D
