I am having some trouble with this one, so any help would be appreciated in deriving the equation. Here is the part that I need help on: Given the rotational inertia of the rod-disk system about the center of mass is 5/24ML^2, derive an expression for the angular speed of the rod-disk system immediately after the collision.

Consider the orbit of a typical comet around the sun, which is marked at five different positions, s, z, u, x , and p. sun a b x z p s u using kepler's second law of planetary motion, rank those positions in order of their relative speeds, with the position for the fastest speed first.

Argon, neon, and xenon are examples of

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
