Now I am supposed to find the magnitude of the vertical acceleration of mass 1, in terms of mass 1, gravity and the tension. I found that a_1= ((m_1*g)-2T)/2m_1 but that isn't right. Any help would be great

Based on the fact that the string is massless, and the system and table are frictionless, how would I find the tension in the string acting on mass 2?

I did this question several times and all I get for acceleration is negative 9.8... static friction for the top block is .60 and kinetic friction for the bottom block is .20... The force is making both blocks move a distance of 5 meters starting from rest. They want to know What is the least...
