Transcribed Image Text:

Blocks A, B, and C are placed as in 1) the adjacent Figure (a = 36.9) and connected by ropes of negligible mass. Both A and B weigh w = 25.0 N each, and the coefficient of kinetic friction between each block and the surface is k = 0.35. A) If Block C descends with constant velocity, find SIX physical quantities. B) If the rope connecting A and B were cut, describe what happens to each block and find TWO physical quantities DIFFERENT to the ones you found in part A). Include in your analysis free-body diagrams showing the forces acting on the blocks. Express FIRST your answers in terms of any or all of the variables w, a, k and g (acceleration due to gravity) and THEN their numerical values.
