While you are operating the Turkish Twist ride at the local amusement park you spot a passenger who ate too much cotton candy and is regretting getting on the ride.
You decrease the angular speed of the cylinder from 4:0 rad/s to 2:0 rad/s in 20:0 revoluations at constant angular acceleration.
(a) What is the angular acceleration during this decrease?
(b) How much time did this speed decrease take?
(c) If the ride has a diameter of 5 meters, what speed will the rider be travelling at after the decrease in speed is complete?
