@Qmechanic You're right. I cannot think of a succinct title, can you?

comment In hydrostatics, is it possible for the bouancy to be greater than the weight of a body?
Oh, sure it was!

I don't follow that last hint =/. I've determined $T=0,08N$, though.

I didn't mean I couldn't draw the FBD. I think I get what you mean - I can consider $T_2+B_2-W_2=0$ for body $1$. Ideal conditions will ensure $T_1=-T_2$.

But is it legitimate to "separate" the system? If the rope is cut, $1$ will probably float upwards, and $2$ will sink, I suppose.

comment why is dark matter the best theory available to explain missing mass problems?
@Argus Some empiric evidence has been collected in favour of the dark matter theory. In fact, a specialist even created a "map" of the possile distribution of dark matter in our galaxy, or some bounded space near us, by certain measurements involving light waves and how they were bent by the gravitational field of dark matter. Make some research.

Right. by the way, this is from an introductory course from an university (a basic common course for the exact sciences and engineering factulty.).

@Ron I'm an absolute rookie here, I can't see things so trivially like you!

@Ron I see. How would you determine the motion of block $1$ through time?

comment Dynamics question. Please help, exam coming soon
@Ron What do you call a "constraint" force? This course is really elementary, so I don't think Lagrangian's will appear. It is basically Cinematics, Vectors, basic Dynamics, rectilinear movement (with constant speed or constant acceleration), and relative movements.
