2. Suppose that a car traveling to the East (+x directionbegins to slow down as it approaches a traffic light. Make a statement concerning its acceleration."
3. In a 400-m relay race the anchorman (the person who runs the last 100 m for team A can run m in 9.8 s. His rival, the anchorman for team B, can cover 100 m in 10.1 s. What is the largest lead the team B runner can have when the team A runner starts the final leg of the race, in order that the team A runner not lose the race?
4. A cart starts from rest and accelerates at 4.0 m/s2 for 5.0 s, then maintain that velocity for 10 s, and then decelerates at the rate of 2.0 m/s2 for 4.0 s. What is the final speed of the car?
