- Homework Statement
- The two bodies shown in the picture have the same mass and are inside a room which is accelerating to the right with ##2 \frac{m}{s^2}##. The coefficient of static friction is the same for both bodies. Determine the minimum value of the coefficient of static friction such that the blocks don't slide with respect to the room and the tension.

- Relevant Equations
- Newton's equations

I wrote the equations for ##m_2## with respect to the room, which are:

##x) T-Fr_1-f_1 *=0##

##y) N_1-P_1=0##

For ##m_1## we hace:

##x) N_2=f_2 *##

##y) T+Fr_2 -P_2=0##

Where ##f*_1## and ##f*_2## are the pseudo-forces and ##Fr_1## and ##Fr_2## are the friction forces that contain ##\mu##

Then I solved for ##\mu## and got ##\mu =0.6##

Are my ideas correct? Because I wasn't sure about the sign of the friction.
