Okay, well I've been working on this assignment forever now, and I have it all correct, but one last bit. Here's the problem. Two blocks connected by a rope of negligible mass are being dragged by a horizontal force F. Suppose that F = 66.0 N, m1 = 10.0 kg, m2 = 20.0 kg, and the coefficient of kinetic friction between each block and the surface is 0.105. The first part asked for the Tension of the rope between the blocks. I found that to be 22N. I have no idea how, because I had to find the acceleration to find the tension. I found the acceleration to be(incorrectly according to webassign) 2.095m/s^2. So my question is how do I find the acceleration? I've done it every way I could see, and got 2.095 every time. Any ideas? One more thing, this problem is due midnight central time.
