10. Blocks X and Y, of masses mx - 5.12 kg and my = 3.22 kg, are connected by a fishing line passing over an essentially frictionless pulley (Figure 12). (a) Show that block X slides up the incline with a posi- tive acceleration. Determine the magnitude of that acceleration. Friction is negligible. (b) Determine the magnitude of the tension in the fishing line. I +X X 35.7 Figure 12 Nelson Chapter 2 Page 96
