Let a be the acceleration of the train and x be the length of the train. Since the two ends of the train passes the electric pole with velocities u and v, it means that the velocity of train changes from u and v over a distance x. Now, v²-u²=2ax. (1)... Let V be the velocity of the middle point of the tain, when it passes electric pole. Since the distance of the middle point of the train from the either end of the train is x/2, it means velocity of the train changes from u to V over a distance x/2. Now, V²-u²=2a(x/2) V²-u²=ax. (2)... From (1)... and (2)... V={(u²+v²)/2}½
