A bucket of water of mass 15.9 kg is suspended by a rope wrapped
around a windlass, that is a solid cylinder with diameter 0.350 m
with mass 12.4 kg . The cylinder pivots on a frictionless axle
through its center. The bucket is released from rest at the top of
a well and falls a distance 10.2 m to the water. You can ignore the
weight of the rope.

A block (mass = 1.2 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1.0 x 10-3 kg·m2), as
the figure shows. Initially the pulley is prevented from rotating
and the block is stationary. Then, the pulley is allowed to rotate
as the block falls. The cord does not slip relative to the pulley
as the block falls. Assume that the radius of the cord around the
pulley remains constant at a...

A frictionless pulley has the shape of a uniform solid cylinder
of mass 2.5 kg and radius 15 cm. A 2.1 kg stone is attached to a
very light wire that is wrapped around the rim of the pulley, and
the system is released from rest. When the stone has lost 3J of
gravitational potential energy, how much kinetic energy does the
pulley have?
The Answer is 1.1 J I just don't know how to reach this
answer.
