Starting from rest, a disk rotates about its central axis withconstant angular acceleration. In 8.0 s, it rotates 20 rad.(a) What was the angular acceleration during this time?____ rad/s2(b) What was the average angular velocity?____ rad/s(c) What is the instantaneous angular velocity of the disk at theend of the 8.0 s?____ rad/s(d) Assuming that the acceleration does not change, through whatadditional angle will the disk turn during the next 7.0 s?____ rad
A 35.0 kg child stands at the center of a 125 kg playground merry-go-round which rotates at 3.10 rad/s. If the child moves to the edge of the merry-go-round, what is the new angular velocity of the system? Model the merry-go-round as a solid disk.
