Question
In the figure, a wheel of radius 0.326 m is mounted
on a frictionless horizontal axis. The rotational
inertia of the wheel about the axis is 0.264 kg.m². A
massless cord wrapped around the wheel's
circumference is attached to a 4.00 kg box. The
system is released from rest. When the box has a
kinetic energy of 3.00 J, what are (a) the wheel's
rotational kinetic energy and (b) the distance the box
has fallen? Assume free-fall acceleration to be equal
to 9.81 m/s².
