^ This is the first case.

(friction) = f = μN = 0.05 (3 x 9.8) = ...? For equilibrium, (T - mgsin30 - f) = 0 ---(1) Mgsin60 - T = 0 ----(2) M = ....

yup i think on right tracxk

Then, you should get two answer... And compare them, identify which is m1, which is m2. Sorry, I'm not good at physics...

np thanks. that was actually a maths exam .. do you reckon its hard??

I learnt all that in physics lessons. Here, we include very little physics in maths. It's okay if you can draw the right free body diagrams.
