thank you sammy, so my a was a negative small decimal. and t1 is > 100 like i said. to my knowledge a negative A means that it did not move correct? therefore t1 must e > 100 to keep it from moving down am i right?

i got 0.13 for a. and T1 tension was 110N which is greater than 100N the gravity force acting down for m1. is this even possible?

for the sake of the question, assume its going to the left. can anyone come up with an answer?

heres how i imagine it. picture the worst case scenario where there is NO incline in this problem, but instead both m1,m2 are hanging straight downward. therefore the down force would be 100N+50N= 150N this force would equal the fres force of m3 and therefore no movement. now if we add this...

god there is so many possibilities... can anyone come up with an ultimate correct answer?

the system only moves to the left because there isn't anything applying it to move in the right direction. can anyone build on that agree?

according to my work, a = 0 because the combined applied force of m1,m2 is less than the res of m3. can anyone verify?

thank you so much for verifying my equations good sir at least now i don't have to doubt my self if they are right or wrong. but yes the geometry is correct because 50sin35 will give you the component of gravity that is parallel to the surface and cos would give you the perpendicular im going...

i can't get my head around the whole thing.. m1 = fnet = ma 100 + (-T1) = 10a m2 = fnet = ma 50sin35 + (T?) + (-T2) = 5a m3 = fres = uFn fres = 150 fnet = ma T2 + (-Fres) = 30a please someone help i have no idea

ive done all that on a separate paper, i came to a conclusion that there is no acceleration but the question fully asks to solve for a... I am so lost i really don't know what to do

oh no sorry about that, i only used 30 because i wanted to do the numbers in my head rather than do sin35. please pay no attention to my writing
