an 8kg flywheel of radius r is
initially at rest. assume the radius of the gyration kG= 0.12m and
the radius of the flywheel r = 0.125m. an object B also of mass 8
kg is attached to a cord that is wrapped around a periphery of the
flywheel. the fly wheel starts to rotate clockwise with angular
velocity. the rotation is resisted by a constant frictional torque
mf in the bearing 1Nm. use the work energy principle to determine
the flywheel angular speed after it has rotated through π/2
radians

A small block on a frictionless horizontal surface has a mass of
0.0280 kg . It is attached to a massless cord passing through a
hole in the surface. (See the figure below (Figure 1) .) The block
is originally revolving at a distance of 0.310 m from the hole with
an angular speed of 1.80 rad/s . The cord is then pulled from
below, shortening the radius of the circle in which the block
revolves to 0.115 m ....
