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

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?

Car
Starting velocity (m/s)
Final velocity (m/s)
Time taken (s)

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?

ST graph

The 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.

12. The gradient of line C
