# Tricky question involving masses, a pulley on incline with friction

Oh!!! I understand now. The force of friction (static) shouldn't oppose each other, because I want to find out the mass it would take just so it would move (up or down) the incline.

There should be two limiting values for m2.

If m2 is very small, then the system will accelerate toward the right. This results in an answer such as m2 < msmall. This is the case you have solved, m2 < 1.24 kg.

If m2 is very large, then the system will accelerate toward the left. This results in an answer such as m2 > mlarge.
