    Angular velocity of a disk

    Homework Statement A disc off a mass m1 is spinning freely at omega1(w1). A second disk of the same radius but smaller mass m2=m1/4 is dropped onto the first , and it sticks. What is the angular velocity of the two disks The Attempt at a Solution I honestly have no idea

    Rolling cylinder on an incline

    A cylinder of a mass M and a radius R starts at the top of a hill at a height h, and rolls to the bottom. At the bottom of the hill, what is its linear velocity, linear momentum, and angular momentum? I believe the the velocity is sqrt((4/3)gh) and the the angular momentum is mvsin(theta)...
