A disc is rotating with ω = 10 rad/s about a fixed central axis which is perpendicular to its plane. The disc has a mass of 2 kg and a radius of 10 cm. A small particle of mass 100 g is slowly placed on the outer circumference of the disc. There is sufficient friction between the disc and the particle. What will be the new angular velocity of the system? a) 10 rad/s b) 9.09 rad/s c) 9.51 rad/s d) Can't conserve angular momentum because of friction

A 10.0 cm diameter uniformly solid disk rotates without friction in the horizontal plane. The disk has a mass of 1.50 kg. A point on the outer rim of the disk has a linear velocity of 2.00 m/s. At time t = 0, a compact 0.5 kg mass is dropped onto the outer rim of the rotating disk. (a) What is the angular momentum [L=I(omega)] of the rotating disk before t = 0? (b) What is the rotational kinetic energy [K=(1/2)I(omega)2] of the disk before t = 0? (c) What is the angular velocity of the rotating disk and compact mass after t = 0? (d) What are the kinetic energies of the disk and the compact mass after t = 0? [Ignore energy due to gravity.]

A solid disk of mass M = 3.5 kg and radius R = 0.85 m rotates in the z-y plane as shown.If, as soon as the angular speed is ω = 17 rad/s, the force is immediately removed and a mass m = 1.1 kg is dropped at r = 0.57 m on the disc and sticks there, what would be the new rotational velocity of the disc in rad/s?

Disk $A$ has a mass $m_{A}=4 \mathrm{kg}$, a radius $r_{A}=300 \mathrm{mm},$ and an initial angular velocity $\omega_{0}=300 \mathrm{rpm}$ clockwise. Disk $B$ has a mitial $m_{B}=1.6 \mathrm{kg}$, a radius $r_{B}=180 \mathrm{mm},$ and is at rest when it is brought into contact with disk $A .$ Knowing that $\mu_{k}=0.35$ between the disks and neglecting bearing friction, determine $(a)$ the angular acceleration of each disk, $(b)$ the reaction at the support $C .$
