A spinning disk of mass 5.0 kg and radius 0.25m is rotating about an axis via its center at 400 rev per min.
i) Determine the angular velocity of the disk in rad/s?
ii) Determine the moment of inertia of the disk?
iii) When it accelerates at a constant rate to 800 rev/min in 8 sec, then find out its angular acceleration?
iv) Determine the constant torque which is required to produce the acceleration?
v) When it reaches that speed then determines the kinetic energy?
vi) If it reaches that speed, find its angular momentum?
