1. What distance will a train stop in if its initial velocity is 23 m/s and its acceleration is -0.25 m/s/s?
2. What distance will a car cover accelerating from 12 m/s to 26 m/s in 14 seconds? What is the acceleration?
3. A person starts at rest and accelerates at 3.2 m/s/s for 3.0 seconds. What is their final velocity? What is their average velocity? What distance do they cover in that time?
4. Steve Apt's group claimed that they fell 3.2 seconds from a cliff into the water. What was their final speed? How high was the cliff? (Use 9.8 m/s/s as the acceleration)
5. A car going 12.7 m/s accelerates for 14 seconds at 2.6 m/s/s. What is its final velocity? What distance does it go during that time?
6. What time will it take you to hit the water off of a 10.0 m board? What speed will you be going when you hit the water? (Use 9.8 m/s/s as the acceleration)
7. A car slows from 42 m/s to 21 m/s over a distance of 84 m. What was the average velocity? What was the time? What was the acceleration?
8. A car accelerates from rest down a hill reaching a final speed of 13.7 m/s over a distance of 56 m. What was the average speed? What was the time? What was the acceleration?
9. A car skids to a halt in 34 m with an acceleration of 8.2 m/s/s. What was the initial velocity?
10. What must be the acceleration of a train in order for it to stop from 12 m/s in a distance of 541 m?
