Two objects of masses m1 and m2 are connected via a massless string and ideal pulleys. The coefficients of friction between m1 and the horizontal surface are ms and mk

a) what condition needs to be met to set the system in motion?

b)assuming that this condition is (barely) met, describe the motion of the system.

c) what is the tension in the string when the objects are in motion?

2. Relevant equations

T=ma

3. The attempt at a solution

a) m2 needs to be slightly heavier than m1

b) m2 will be slightly heavier, the tension in the string increases causing m1 to move forward since they're not in equilibrium.

c) ????

This was on a test, but I got it wrong... he wanted actual equations proving everything and i had no idea how to do any of this. I was just really confused. Can anyone explain it to me?
