I got 0. Not sure if thats right though, Wotd everyone else get??

how can the max length be 0?

 

[ashwin]

it didnt ask for the max length, but the length at which M would be closest to the floor. When x=0, the rope is the straightest it can get, which means its closest to the ground. Thats what i thought anyway

One thing I will ask though is, for 1a, is a 0 after a dec place considered as a sig fig? like 0.0392 - is that 3 sig figs or 4?

That's 3 sig figs.. the 0 isn't counted.

i found up to 6 easy but then it went downhill fast
i hav been used to my school setting difficult exam papers where 80% can b considered a fairly decent mark

all the ppl saying goodbye uai of 90 .. have you heard of scaling??

That's true... Laz mentioned it a few times.. something about alignment.. I didn't get it, but by the looks of it, it's supposed to be something good.
