Question 16 was so tough, and I didn't realise there was the last page until 10 minutes remaining

Woooooo, I totally screwed that one up.
If I didn't have extra units I'd be in a bad state right now, damn.

Only doing this crappy subject because of my parents anyway, I'm glad to be done with it.

It was fine tbh. Lost 7 marks defs for the last two qs and the find x for sin a = sin b qs. Hope I get 85+ fml

All I remember is that you had to know that the absolute value of r<1 and then you rearrange the formula to make r the subject and substitute that in

what did everyone get for question 10 where it asked for how many times the velocity changed direction?

I think I chose 2 because you count how many times it goes from positive to negative or negative to positive. But I think might have misread the graph, not sure lmao

yayy u got it right haha. its cos the top half is the positive direction and vice versa. the stationary points only highlight a change in speed i.e. like it slowed down more
