Your computer hard drive rotates at a rate of 10,000rpm. if i turn off the computer and it takes 17s for it to come to a complete stop, what is the angular acceleration of this motion? show your work

Initial angular frequency is given as

now convert it into rounds per seconds

now initial angular speed is given as

now finally it comes to rest in t = 17 s

now we can use kinematics equation to find the angular acceleration

so angular acceleration will be 61.6 rad/s^2
