Consult Interactive Solution 2.22 before beginning this problem. A car is traveling along a straight road at a velocity of +25.0 m/s when its engine cuts out. For the next 2.25 seconds, the car slows down, and its average acceleration is a1 . For the next 5.23 seconds, the car slows down further, and its average acceleration is a2. The velocity of the car at the end of the 7.48-second period is +16.5 m/s. The ratio of the average acceleration values is a1/a2 = 1.84. Find the velocity of the car at the end of the initial 2.25-second interval.
