Consult Interactive Solution 2.22 before beginning this problem. A car is traveling along a straight road at a velocity of +39.7 m/s when its engine cuts out. For the next 2.18 seconds, the car slows down, and its average acceleration is . For the next 6.86 seconds, the car slows down further, and its average acceleration is . The velocity of the car at the end of the 9.04-second period is +20.2 m/s. The ratio of the average acceleration values is  = 1.22. Find the velocity of the car at the end of the initial 2.18-second interval.

1) A Red Car and a Blue Truck are driving down a winding road. Through the first curve in the road, the Red Car is driving twice as fast as the Blue Truck. The second curve is half the radius of the first, which causes the Red Car to slow down to half the speed of the Blue Truck to drive around the curve. Rank the acceleration each vehicle experiences in each curve from largest to smallest. -blue truck in...
