Question
If a rotating disk starts from rest and ends up at 200 rpm in 4 seconds, what is the angular acceleration? How many revolutions occur during the process?
If that same disk, after the power is turned off comes to rest in 20 seconds, what is the angular deceleration?
If that same disk, after the power is turned off comes to rest in 20 seconds, what is the angular deceleration?
