Question
100%
A child of mass m = 40 kg is initially placed on the
edge of a uniform disk, of mass M = 100 kg and
radius R = 2.0 m, which is rotating with an angular
speed w_i about a vertical axis passing through its
center. The child moves on a radius and stops at
the distance a = 1.5 m from the edge of the disk as
indicated. If the final angular speed of the disk-child
system is w_f= 4.5 rad/s, determine the initial
angular speed w_i.
