Homework Statement


Three forces act on a particle. What is the direction of the resultant of these forces.
The three forces are: a 65 N force at 30 degrees, a 30N force at 180 degress (going towards the negative x-direction), and a 20 N force at 250 degrees (in the negative x and y directions) the object being at the origin


Homework Equations





The Attempt at a Solution


i just want to know if i could just find the resultant of two forces, than take that resultant and the remaining force and take the resultant of that and find the angle

Vector addition is commutative: (A+B) + C = A + (B+C). So yeah, that should work.
 
thanks
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
