A dual pulley with an inner diameter of 100 cm and an outer diameter of 300 cm supports a pair of identical, 32.5 kg weights. The left weight hangs by an inextensible cable wrapped around the inner pulley. The right weight is supported by an inextensible cable wrapped around the outer pulley, looped around a smaller, massless pulley, and attached to a hook in the ceiling.

Question

A dual pulley with an inner diameter of 100 cm and an outer diameter of 300 cm supports a pair of
identical, 32.5 kg weights. The left weight hangs by an inextensible cable wrapped around the inner
pulley. The right weight is supported by an inextensible cable wrapped around the outer pulley,
looped around a smaller, massless pulley, and attached to a hook in the ceiling. If the dual pulley
has a mass of 2.5 kg and a radius of gyration of 38 cm, find the speed of the left weight after it has
risen 2 m.
The left weight rises at 2.44
o m/s
Round answer to 3 significant figures.
