2) A uniform solid disk starts at 52 rad/s. To rest, it does 3900J of work. It has a radius of 1.2M. How long does it take to stop and how far does it go? (1/2mr^2)
3) A wheel is rotating at a constant rotational acceleration. What is true?
4) If you release a hoop, disk, and sphere at the same time from a ramp, what will have the greatest rotational acceleration.
5) 2 cylinders rotate counter clockwise are brought together. What is their rotational speed after? (One wheel has constants all of 1, the second one has constants all of 2)
