potters wheel uniform cylinder i5mr2 radius 5 meteres and mass 15 kg

A potters wheel is a uniform cylinder (I=.5mr^2) with a radius of .5 meteres and a mass of 15 kg. Calculate the applied torque need to accelerate at a rate of 2 radians/s/s. Calculate the rotational energy the wheel has at its final velocity after 10 seconds of rotating.
