3 blocks are pulled at a constant speed. what is the tension in the other ropes?

the 3 blocks have a mass of M1= 3kg M2 = 2 kg M3 = 7 kg
tension in rope between block 1 and 2 is unknown T1
tension in rope between block 2 and 3 is 10N (T2)
tension in rope in front of block 3 is unknown (T3)

Hint: there are other forces acting here - what are they and why?
