From Newton's First Law, we can see that the acceleration it is simply the ratio of the Force on the mass. In this case, the mass is the sum of the the mass of each car, that is:mass = 2300 kg + 2500 kg = 4800 kg So the formula is:acceleration = Force / massacceleration = 18,000 N / 4800 kgacceleration = 3.75 m/s^2 In 2 significant figures:acceleration = 3.8 m/s^2
