State the relation between c, and cy for an ideal gas and use it to calculate the molar heat capacity in an isobaric process for: (i) a monoatomic gas; (ii) a diatomic gas

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.
