The maximum acceleration of a car while towing a second car twice its mass is one-third of its acceleration when not towing. This is because the total mass being accelerated is three times the mass of the car alone (the car plus twice its mass), and acceleration (a) is inversely proportional to mass (m) when force (F) is constant, as per Newton's second law (F = ma).
