A model train accelerated from 0.15 m/s0.15 \text{ m/s}0.15 m/s to 0.65 m/s0.65 \text{ m/s}0.65 m/s. The acceleration of the model train was 0.050 m/s20.050 \text{ m/s}^20.050 m/s2. The work done by the resultant force to accelerate the train was 0.96 J0.96 \text{ J}0.96 J. Calculate the magnitude of the resultant force needed to accelerate the train.
