Ok, thanks tiny-tim. I guess I was looking for an easier, symmetric way of doing the system of equations for these type of problems, but I guess one has to always be sure and find the direction of the net force/acceleration first...
Hey guys. The last couple days, I've been poring over problems like this:
"Block A with a mass of 10kg rests on a 30 degrees incline. The coefficient of kinetic friction is 0.20. The attached spring is parallel to the incline and passes over a massless, frictionless pulley at the top. Block...
Sorry to resurrect this old topic. I've had a problem exactly like this a couple nights ago, and I spent hours trying to examine all of the angles. In this case, we're assuming that Block 1 is accelerating downwards, thereby pulling Block 2 up the incline. If this is true, then the solution is...
