natasha.aries 2 years ago a man running on a straight path at 3 meters per second accelerates uniformly to a speed of 5.23 meters per second in 9.65 seconds. What is the total distance traveled? What formula can i use?

1. VeritasVosLiberabit

$x _{f}=x _{i}+v _{1}\Delta t+\frac{ 1 }{ 2 }a \Delta t ^{2}$

2. natasha.aries

whats a?

3. VeritasVosLiberabit

a would be the acceleration.

4. natasha.aries

what would it be in this case though? like what number?

5. VeritasVosLiberabit

Actually the first equation you should use is this one $v _{f}=v _{i}+a \Delta t$

6. VeritasVosLiberabit

7. natasha.aries

ohh so first we solve for acceleration and then plug it into the other formula?

8. VeritasVosLiberabit

then you could actually just use the formula $v _{f}^{2}=v _{i}^{2}+2a \Delta x$ and compute the total distance.

9. VeritasVosLiberabit

so you actually won't even need the first formula, so you can disregard it.

what did u end up getting for acceleration because i got 4 and then did the problem and got it wrong..

11. VeritasVosLiberabit

12. natasha.aries

just kidding!

13. natasha.aries

i got it! haha i divided wrong

14. VeritasVosLiberabit

you should setup the problem and show me how you did it. but the answer came out to be 39.7

15. VeritasVosLiberabit

ok good job :)

16. natasha.aries

lol yeah i figured it out haha i have some more questions and i dont know what formulas to use and i have my test tomorrow, would u mind helping me out?

17. natasha.aries

i dont mind reposting it so i could give u the best answer but would u mind helping me?

18. VeritasVosLiberabit

sure. could you make a new thread for it though? This one is cluttered now.

19. natasha.aries

yes! no problem! gracias
