1. Consider two blocks that are attached by a string. Block 1 (mass of 2 kg) lays on a flat plane. Block 2(mass of 3 kg) hangs freely off the edge of the plane. In the absence of friction, Block 2 would fall and the string would pull Block 1 towards the edge. Find the static coefficient of friction needed to keep Block 1 at its starting position.
