Question #19218

a force is applied to the rim of a disk that can rotate like a merry go round, so as to change its angular velocity. Its initial and final angular velocities, respectively, for four situations are:(1)minus2 rad/s, minus5 rad/s(2) 2 rad/s, minus 5 rad/s(3) 2 rad/s, 5 rad/s (4)minus 2 rad/s, 5 rad/s. Rank the situations according to work done by the torque due to the force, greatest first. Also give reason if they are all equal.
