In the figure above, two blocks are connected by a massless string
that runs over two pulleys. Block 1 has mass m1=5 kg and block 2
has mass m2=2 kg.
(a) For m1, draw the free-body diagram, and write out E F, = may.
(b) For m2, draw the free-body diagram, and write out E F, = m ay.
(c) Use your equations from (a) and (b) to solve for the tension in the
string and the acceleration of the blocks.
(Hints: the tension is not equal to either of the weights. If you do not
know the direction of the accelerations or tension forces, make a
consistent choice, and see if your answer comes out positive or
negative.)
