Learning Goal:
To practice Problem-Solving Strategy 9.1 Rotational
Energy.
Part C
How far must the stone fall so that the pulley has 4.30 J of kinetic energy?
A frictionless pulley has the shape of a uniform solid disk of
mass 6.00 kg and radius 19.0 cm . A 3.20 kg stone is
attached to a very light wire that is wrapped around the rim
of the pulley(Figure 1), and the stone is released from rest.
As it falls down, the wire unwinds without stretching or
slipping, causing the pulley to rotate. How far must the
stone fall so that the pulley has 4.30 J of kinetic energy?
Express your answer numerically in meters to three significant figures.
h = .15 m

To see if your results are reasonable, you can compare the final velocity of the stone as it falls down unwinding the wire
from the pulley, to the velocity the stone would have if falling the same distance while unconnected to the pulley. What is
the velocity of an untethered stone after falling 0.283 m from rest?
Express your answer numerically in meters per second.
