1.Here is the diagram of the problem.(adsbygoogle = window.adsbygoogle || []).push({});

Two blocks attached by a string (see figure) slide down a 16° incline. Block 1 has mass m1 = 0.79 kg and block 2 has mass m2 = 0.27 kg. In addition, the kinetic coefficients of friction between the blocks and the incline are 0.30 for block 1 and 0.20 for block 2.

(a) Find the magnitude of the acceleration of the blocks.

(b) Find the tension in the string.

Equation:

Fk = Uk + FN

F = MA

(for individual mass)

Fn = mg cos theta

Fg = mg

Fparallel = mg sin theta

My trouble is how to start this. If this was just 1 mass, I would have no trouble but I get thrown off/confuse once they add a string and another mass.

Can someone suggest on how I start this?

I was thinking that M1 has the same Acc. as M2 but then I saw that they each have different kinetic coefficients. Can someone suggest on how to start this problem?
