How to Calculate T2 in a Massless Strings System?

[larla]

help me!

Homework Statement

Three blocks on a frictionless surface are connected by massless strings, with M1 = 1.80 kg, M2 = 2.80 kg, and M3 = 3.70 kg. Due to the force F acting on M3, as shown, the system accelerates to the right. Given that T1 is 2.70 N, calculate T2

Homework Equations

m1(t1/m1+m2)

The Attempt at a Solution

I don't exactly know what to do...

What have you done so far? Are you familiar with free body diagrams?
