1&2. A motorbike moves along a road at 25m/s.

Calculate ..

1. The distance moved in 50s.

• A). 2 m
• B). 0.5 m
• C). 125 m
• D). 1.25 km

2. The time taken to travel 2 kilometres.

• A). 4 s
• B). 80 s
• C). 0.08 s
• D). 40 s

3. Which of these is the correct formula for acceleration?

• A). change in velocity x time taken
• B). change in velocity ÷ time taken
• C). velocity x time taken
• D). velocity ÷ time taken

4. A train accelerates from 10 m/s to 50 m/s in 20 seconds. The acceleration is:

• A). 2 m/s2
• B). 2.5 m/s2
• C). 800 m/s2
• D). 1000 m/s2

5+6. In a formula 1 car race the acceleration of the first few cars was measured from the start grid.
What are the missing values?

 Starting velocity (m/s) Final velocity (m/s) Time taken (s) acceleration (m/s2) 5. 5 30 ? 0 5 6 25 130 750 5 6. 0 ? 72 36 2 0.5 12 6

7. If a car accelerates at - 3 m/s2, what does this mean?

• A). It is moving backwards at a constant speed
• B). It is slowing down
• C). It is accelerating but 3 m/s2 less than before
• D). It is accelerating, but the resultant force is backwards

8. Which of these 4 distance (s) -time (t) graphs shows a car accelerating?

9-12: This velocity-time graph shows the journey of a bus as it moves away from a road junction.

What quantity is shown by...

9. The gradient of line A?
10. Line B?
11. The area under the line?
