A car moves along an x axis through a distance of 950 m,starting at rest (at x = 0) and ending at rest (atx = 950 m). Through the first 1/4 of that distance, itsacceleration is +6.25 m/s2. Through the next 3/4 of that distance, its acceleration is -2.08 m/s2. What are(a) its travel time through the 950 m and(b) its maximum speed?
