Calculate the acceleration of a 310,000 kg jumbo jet just before takeoff when the thrust on the aircraft is 130,000 Newton express the answer to two significant figures in include the appropriate units.

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.
