I seem to be having some problems solving this. First of all, I figured out what the acceleration of the blocks would be without friction. I'm not sure if this is correct or not but I found that a = 5.0 m/s/s. I did this by using Fp - Tension = ma and, T = ma. Then I factored in kinetic friction and I am getting ~.66 m/s/s using the same two equations except subtracting u*m*g from the left of each equation. That's not correct, is it? Going from 5 to less than 1 seems wrong to me.. Anyone know what I'm doing wrong?
