45kg mass particle goes at 3m / s and collides with the upper edge
of a uniform density disk with a mass of 175kg and a radius of
1.25m. The disk before collision was at rest. Without considering
any type of friction, what will be the magnitude of the angular
velocity of the disk with the particle attached to its edge just
after the collision?

4)A large disk of mass Md and radius R is spinning in a horizontal plane about a vertical axis through its center with a given angular velocity of omega. A person of mass Mp (initially at the center of the disk and not spinning, let's say) then walks out to the edge of the disk (yes, the disk is that large!). Find the final angular velocity of the disk (with the person standing on its edge).Treat the person as a...

A uniform, solid cylinder with mass 3M and radius 2R rests on a
horizontal tabletop. A string is attached by a yoke to a
frictionless axle through the center of the cylinder so that the
cylinder can rotate about the axle. The string runs over a

A spherical asteroid with radius r = 123 m and mass M= 2.25×1010kg rotates about an axis at four revolutions per day. A "tug" spaceship attaches itself to the asteroid's south pole (as defined by the axis of rotation) and fires its engine, applying a force Ftangentially to the asteroid's surface as shown in the figure. If F = 285 N, how long will it take the tug to rotate the asteroid's axis of rotation through an angle of 5.0∘...
