An 8.0-kg block and a 10-kg block, connected by a rope that passes over a frictionless peg, slide on frictionless in- cline, (Figure 4-56). (a) Find the acceleration of the blocks and the tension in the rope. (b) The two blocks are replaced by two others of masses m1 and m2 such that there is no acceleration. Find whatever information you can about the masses of these two new blocks.
