In a tug-of-war, a jeep of mass 1200 kg and a tractor of mass 2200 kg pull on a horizontal rope in opposite directions. At one instant, the tractor pulls on the rope with a force of 1.40×104 N while its wheels push horizontally against the ground with a force of 1.50×104 N. Calculate the instantaneous accelerations of the tractor and of the jeep. Assume the rope does not stretch or break.
