A car is traveling along a straight road at a velocity of +32.7 m/s when its engine cuts out. For the next 1.04 seconds, the car slows down, and its average acceleration is . For the next 5.23 seconds, the car slows down further, and its average acceleration is . The velocity of the car at the end of the 6.27-second period is +25.5 m/s. The ratio of the average acceleration values is = 1.36. Find the velocity of the car at the end of the initial 1.04-second interval.
