Question: An airliner arrives at the terminal, and the engines are shut off. The rotor of one of the engines has an initial clockwise angular speed

An airliner arrives at the terminal, and the engines are shut off. The rotor of one of the engines has an initial clockwise angular speed of 2 000 rad/s. The engine’s rotation slows with an angular acceleration of magnitude 80.0 rad/s2.
(a) Determine the angular speed after 10.0 s.
(b) How long does it take the rotor to come to rest?
