A mass m1 hangs from one end of a string passing over a frictionless, massless pulley. A
second frictionless, massless pulley hangs from the other end of the string (see the figure
below). Masses m2 and m3 hang from a second string passing over this second pulley. Find the
acceleration of the three masses, and find the tensions in the two strings.
