As shown in Fig. , block A, B, and C
are connected with a thin rope and
pulleys. The mass of block A, B, and
C, are m, 3m, 5m, respectively. If
there is no friction between all
contacting surfaces, and the rope
and the pulleys are massless, which
of the following statement is
correct regarding the aq the
acceleration of block A, and as the
acceleration of block B?
A
