Tension Problem Please help!
Ok so i got this question
Look at the attached diagram
Althoughin the diagram i drew it doesn't look like it , Mass 1 on the incline is heavier than Mass 2 and the accleration is to the left.
The ramp is frictionless and the strings and pulleys are assumed to be massless
Find the acceleration on m2 and the string forces.
Now normally i wouldn't have trouble iwht something like this but that extra pulley throws me off
normally i'd think for the sum of the forces on mass 1
[tex] M_{1}a = M_{1} g Sin \theta - T [/tex]
and
[tex] M_{2}a = T - M_{2} g [/tex]
this however does not yield the answer after i plugged in Mass 1 = 0.4kg, Mass 2 = 0.2kg, and Theta = 30 degrees.
COuld you perhaps point out where my mistake lies and point me in the right direction. How does that left pulley influence that motion.
For the left pulley considering the mass and pulley and the wall alone
[tex] M_{1} g - T = M_{1} a [/tex] and
T = reaction force of the wall??
Am i going off on a tangent, is this totally necessary for finding the acceleration on M2??
