For me, it is obvious that I have to divide 0.195 with 2, but I am not sure if 0.07 also have to be divided with 2 since the carton is
skewed.
So your are saying, that I also have to divide 0.07 with 2?

Homework Equations
∑Mb = m*a*d
The Attempt at a Solution
Using the formula below i get:
m*g*cos(0)*(0.07/2)-m*g*sin(0)*(195/2)=m*a*h
And I get 3.52 m/s^2
Is it correct?
First of all, thank you for your feedback.
I know that I am not done, as you say I need to find the answer in Cartesian form in Denmark (a+jb), that is why I am asking if i have to use the formula:
which I am confirmed that I have to.
And I can see, what you mean with the equal sign. Thank you.

The way i have simplified it:
I do not know it is the way to do it.
But if so, now I need to give the answer in cartesian form, and I think I need to use the formula:
meaning it will look like:
Anyone who can tell me if I am on the right...

Homework Equations
r=sqrt(a^2+b^2)
θ=arg(z)
tan(θ)=b/a
The Attempt at a Solution
for a)[/B]
finding the polar form:
r=sqrt(-3^2+(-4)^2)=sqrt(7)
θ=arg(z)
tan(θ)=-4/-3 = 53.13 °
300-53.13=306.87°
-3-j4=sqrt(7)*(cos(306.87+j306.87)
I don't know if my answer is correct...
