Rotating object rotates at 1500 rpm then switched off the motor. after doing so how much time it takes to completely stops and how much revolution. linear velocity is 7.85 m/s and acceleration is 7.85 m/s^2. 3 blade radius is 63.5 cm. used material is Al6061. Take total mass of rotating object is 15.4 kg. 3 blade and rod are hollow type object that's why photo and given 15.4 kg may vary.
