Final Answer

9.82 In Fig. P9.82, the cylinder Figure P9.82
and pulley turn without friction about
stationary horizontal axles that pass
through their centers. A light rope is
wrapped around the cylinder, passes
over the pulley, and has a 3.00 kg box
suspended from its free end. There is
no slipping between the rope and the
pulley surface. The uniform cylinder
has mass 5.00 kg and radius 40.0 cm. The pulley is a uniform disk with
mass 2.00 kg and radius 20.0 cm. The box is released from rest and de-
scends as the rope unwraps from the cylinder. Find the speed of the box
when it has fallen 2.50 m.
