A block (block 5) of mass m5 = 2.3 kg hangs from the end of a (massless) string which runs over a (massless frictionless) pulley. The other end of the string is connected to another block (block 4) of mass m4 = 6.1 kg on a surface inclined at an angle of θ = 27o above the horizontal. The situation is shown below. a) Assuming there is no friction between block 4 and the inclined plane, find the acceleration (magnitude...
