The figure below shows two boxes connected to each other by a
light cable that passes over a pulley with negligible friction. The
box of mass m1 = 4.20 kg
lies on a horizontal table with negligible friction, while the box
of mass m2 = 11.7 kg hangs
vertically.
(a)
What is the magnitude of the acceleration of each box (in
m/s2)? (Here, a1 is the
acceleration of m1, and
a2 is the acceleration of
m2.) a1=
? a2=?
(b)
What is the tension in the cable (in N)?
