The acceleration of the system can be found using the formula a = (m1 - m2)g / (m1 + m2), where m1 is the mass of the larger object, m2 is the mass of the smaller object, and g is the acceleration due to gravity. Plugging in the given values, we get a = (9 kg - 2 kg)(9.8 m/s^2) / (9 kg + 2 kg) = 6.2 m/s^2. Therefore, the correct answer is B.
