Oil dropping down the inner side of a tube confirms amine. This is what analysis ?

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.

Both independent and dependent clauses

Can anyone plz answer any of these. even if its one it will
