Homework Statement
Ive been told to perform 2-3 Picard Iterations on the following problem
Homework Equations
y'' = 6y^2
With initial conditions:
y(0) = 0
y'(0)= -2
The Attempt at a Solution
In class we've gone through how to perform picard iterations and it has been easy so far...
Heres a question I am stuck with
Crosslinked polymers consisting of 62 wt% ethylene and 38 wt% propylene may have elastic properties similar those for natural rubber. For a copolymer of this composition, determine the fraction of the ethylene mer.

I don't quite understand 2 :(
Edit:oops soz, ment to edit and get rid of the part where I said "where do u get k from"
Edit2: aw crap, I still have no idea for those questions

Two physics students conduct the following experiment from a very high bridge. Thao drops a 1.5kg shot put from a vertical height of 60m while at exactly the same time Benjamin throws a 100g mass with an initial downwards velocity of 10 m/s from a point 10m above Thao.
At what time will the...

Solve for x:
|3x+2|=2|3-x|
Done that part
b
Sketch the graph of y=|2x|-|3-x| and hence find all solutions of
|2x|=|3-x|+2
I have sketched the graph however I don't know what to do for "and hence find all solutions of
|2x|=|3-x|+2"
Please help :D Any help would be much...
