    I think the logic point it is the the displacement graph must have a POI between the two SPs, therefore acceleration has to equal 0

    Yep I got that, it wasnt too hard. You just had to get the right angle. One angle was 60 degrees and one side was 1. Then you use the tan ratio to solve

    No because for An, n was nth withdrawal. And he was only withdrawing once a year (after 4th quarter of each year)

    I think 24 years? Im not sure if I did it correctly.. However I do remember my equation being 1,000,000 (1.015)^4n - 80,000 ( (1.015)^4n -1) / (1.015)^4 - 1)

    Oh that one was horrendous, however it was similar to a question that popped in my trials

    I did 1 - (0.98)^n = 0.4 and went from there
