Homework Statement
The original problem with statement is http://images3a.snapfish.com/232323232%7Ffp733%3B9%3Enu%3D52%3A%3A%3E379%3E256%3EWSNRCG%3D335%3A728%3A%3B4347nu0mrj".
Homework Equations
Newton's Laws 1-3
The Attempt at a Solution
Note that the table is frictionless, the only friction is between the two boxes
So first:
[tex] \mu = .45 [/tex]
and the T on M1 is
[tex] T_{m_{1}}=F_{a} [/tex]
and T on M2 is
[tex] T_{m_{2}}=-F_{a} [/tex]
and
[tex] F_{n_{1}}=m_{1}g [/tex]
[tex] F_{n_{2}}=m_{1}g+m_{2}g [/tex]
So the friction force on M1 from M2 should be:
[tex] F_{ \mu_{1}} = \mu F_{n_{1}} [/tex]
and the friction on M2 from M1 should be:
[tex] F_{ \mu_{2}}=\mu F_{n_{1}} [/tex]
So i am kind of confused as to how I should use the T forces... here is what I did:
[tex] F_{net_{x}} = F_{a}+F_{\mu_{1}-T-F_{\mu_{2}}=0 [/tex]
[tex] F_{net_{y}}=F_{n_{1}}+F_{n_{2}}-m_{1}g-m_{2}g=0 [/tex]
is that right? I am not sure how to set up T because for m1 t is opposite the friction force and for m2 T is opposite the Fa force... should I set up a relationship that way to do this correctly?
