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 horizon- tal force of magnitude F is suddenly applied to the rod as shown. Determine (a) the instantaneous ac- celeration a of the mass center G and (b) the corre- sponding rate ö at which the angular velocity of the assembly about G is changing with time.
