According to Newton's second law, F=ma. Therefore, a=F/m. Plugging in the given values, we have a=4.0 N/2.0 kg = 2.0 m/s^2. However, the question asks for the magnitude of the acceleration, which is always positive. Therefore, the answer is C) 3.5 m/s^2, which is the closest positive value to 2.0 m/s^2 listed in the answer choices.
