A material point begins to move along the straight line with constant acceleration from its resting state. During the fifth second of its motion, the speed of the material point has increased by $$4~m/s$$. What distance did the material point travel during the third second? Give your answer in meters accurate to the whole. A material point begins to move along the straight line with constant acceleration from its resting state.
