А
Three blocks, labeled A, B, and C, are connected by essentially massless strings that run over essentially massless and frictionless pulleys (as shown in Figure A
above). Block A hangs straight down. The string from block A connects to block B which is sliding up and to the left along an inclined plane. The plane is
inclined at an angle of theta = 0 = 52 degrees away from vertical. The coefficient of kinetic friction between block B and the plane is 0.38. Block B is
connected by a different string to block C which hangs straight down.
Block A has a mass of 4.1 kg. Block B has a mass of 3.7 kg. Block C has a mass of 2.5 kg. Block A is moving down and block C is moving up (the strings do not
stretch).
The only significant forces acting on the blocks are friction acting on block B, normal forces, tension forces, and gravity (with g = 9.81 m/s²). Calculate the
%3D
acceleration (in units of meters per second squared) of block A. For block A, a downward acceleration is considered positive, and the sign of your answer is
