2. Question #1
Light from the sun reaches the earth in 498 s. If the sun is x 1011 m from the earth, how fast(m/s) does light travel in space?

3. Question #1 Solution Given: RTF: Formula Solution:
∴ Light travels at 3.00 x 108 m/s in space.

4. Question #2
A bullet is fired at 660 m/s and strikes a target meters away. What is the duration of the bullet’s flight?

5. Question #2 Solution Given: RTF: Formula Solution:
∴ It takes 0.3 s for the bullet to travel 200m.

6. Question #3
What is the average speed (m/s) of a runner who completes a 5.00 km race in min?

7. Question #3 Solution Given: RTF: Formula Solution:
∴ The average speed is 4.07 m/s.

8. Question #4
An amusement park carousel travels at a speed of 8.0 m/s. If the circular track of the carousel has a radius of 10.3 m, how many seconds will it take for the carousel to make one complete revolution?

9. Question #4 Solution Given: RTF: Formula Solution:
∴ It takes 8.1 s to complete the revolution.

10. Question #5
During a 400 meter run at a track meet the runner in lane 1 will start and finish at the same point. If it takes seconds for her to run the race what is her velocity?

11. Question #5 Solution Given: RTF: Formula Solution:
∴ Runner traveled at 0m/s around the track.

12. Question #6
What is the velocity of a car traveling north east on 401 if it takes 2 hours to reach Toronto 200 km away?

13. Question #6 Solution Given: RTF: Formula Solution:
∴ Velocity is 27.8 m/s [NE].

14. Question #7
A car starts from rest and reaches a velocity of 22.0 m/s in 20.0 seconds. What is its acceleration?

15. Question #7 Solution Given: RTF: Formula Solution:
∴ Acceleration is 1.1m/s2 [F].

16. Question #8
How long would the same car, from #7, take to go from 22.0 m/s to 30.0 m/s with the same acceleration?

17. Question #8 Solution Given: RTF: Formula Solution:
∴ It will take 7.3 s to accelerate from 22m/s [F]
to 30 m/s [F].

18. Question #9
How much time does a car with an acceleration of 2 m/s2 take to go from 10 m/s to 30 m/s?

19. Question #9 Solution Given: RTF: Formula Solution:
∴ It will take 10s to accelerate to 30m/s[F].

20. Question #10
What is the acceleration of a racing car if its velocity is decreased uniformly from 66 m/s to 44 m/s during an 11 second period?

21. Question #10 Solution Given: RTF: Formula Solution:
∴ Acceleration is -2m/s2 [F] or 2m/s2 [B].

22. Question #11
A spacecraft traveling at 1200 m/s is uniformly accelerated at the rate of 150 m/s2 by burning its second stage rocket. If the rocket burns for 18 s, what is the final velocity of the craft?

23. Question #11 Solution Given: RTF: Formula Solution:
∴ Final velocity of the spacecraft
is 3900 m/s [F].
