The angular acceleration = (440 - 210)rpm/5.1 s
= 230/ (60*5.1) rev/s^2
= 0.752 rev/s^2 = 4.72 rad/s^2

The blades of a fan running at low speed turn at 240rpm . When the fan is switched to high speed, the rotation rate increases uniformly to 340rpm in 5.75s . What is the magnitude of the angular acceleration of the blades? (rad/s^2) How many revolutions do the blades go through while the fan is accelerating? (rev)
The blades of a fan running at low speed turn at 290 rpm. When the fan is switched to high speed, the rotation rate increases uniformly to 450 rpm in 5.05 s. What is the angular displacement of the blades during that time interval?
6. When a 2.75-kg fan, having blades 18.5 cm long, is turned off, its angular speed decreases uniformly from 10.0 rad/s to 6.30 rad/s in 5.00 s.

An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s). If a particular disk is spun at 675.4 rad/s while it is being read, and then is allowed to come to rest over 0.167 seconds, what is the magnitude of the average angular acceleration of the disk? rad average angular acceleration If the disk is 0.12 m in diameter, what...
