13) Two blocks connected by a rope of
negligible mass are being dragged
by a horizontal force (Fig. P5.13).
Suppose F = 68.0 N, $m_1$ = 12.0 kg,
$m_2$ = 18.0 kg, and the coefficient
of kinetic friction between each
block and the surface is 0.100.
a) Draw a free-body diagram for
each block. Determine (b) the
acceleration of the system and
c) the tension T in the rope.
$m_1$ T $m_2$ $\vec{F}$

d) Determine the acceleration of
the system if everything is the same
as given in the text, except that the
force, $\vec{F}$, instead of being horizontal, is
directed at an angle of 30.0 degrees
above the horizontal.
