a disc of mass m= 0.5kg is rotating at an initial angular velocity of 5 rad/sec. If it changes its angular velocity at a rate of 2 rad/sec^2 find:
1. the disc final angular velocity at 10 second
2. the disc angular displacement of the disc at the end of 10seconds.
3.Calculate the initial rotational kinetic energy of the disc.
4.what is the final rotational kinetic energy of the disc at the end of 10seconds.
5. compute the work done on the disk during the given time.
