1991/1996 Q7 Easy - How about 1990? (1 Viewer)

[kpq_sniper017]

I was looking at the 1990 HSC exam (Q7), and I surprised myself by pulling most of it out. How would you rate the difficulty of 1990 Q7? According to stats, the paper as a whole was difficult (dunno about Q7 alone though).
IMO, if I could do it, it mustn't have been very hard by standards.
BTW. Didn't get b(iv) because I made a mistake in (iii).

I thought last years 7(b) wasnt that hard. For (i) and (ii) i used basically 2unit applications of calculus to physical world and physics projectile motion knowledge. I did it a few days after i taught myself projectile motion, and once i realised there were two possible situations in (iii) i found it pretty easy. Is it just me or was it easy, because im sure ive seen much harder.
