Acar moves along an x axis through a distance of 980 m, starting at rest (at x = 0) and ending at rest (at x = 980 m). through the first 1/4 of that distance, its acceleration is + 4.20 m/s^2. through the next 3/4 of that distance, its acceleration is - 1.40 m/s2. what are (a) its travel time through the 980 m and (b) its maximum speed?
