/The rotational kinetic energy for an object changes to 150 j from 50 j.if the angular acceleration for the motion is 0.5 rev/s^2 and the angular displacement during this change is delta-theta= 50 rev,find the (a) moment of inertia I,(b) initial velocity w0(omega zero) and final velocity w(omega),(c)the change in the angular momentum,(d)the torque and (e)the power for this change.
