A man on a railroad platform attempts to measure the length of a train car by walking the length of the train and keeping the length of his stride a constant 82 cm per step. After he has paced off 12 steps from the front of the train it begins to move, in the direction opposite to his, with an acceleration of 0.4 m/s2. The end of the train passes him 10 s later, after he has walked another 20 steps. Determine the length of the train car.
