A futuristic magnetic levitation train weighing 4.5 × 10 4 kg is moving at 0.81c (c is the speed of light). The rate of change of energy with respect to speed (dE/dv) represents the energy needed for each 1.0 m/s increase in speed. Determine the extra energy required to raise the train's speed by 1.0 m/s.
