## natasha.aries Group Title 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? one year ago one year ago

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

2. natasha.aries Group Title

whats a?

3. VeritasVosLiberabit Group Title

a would be the acceleration.

4. natasha.aries Group Title

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

5. VeritasVosLiberabit Group Title

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

6. VeritasVosLiberabit Group Title

7. natasha.aries Group Title

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

8. VeritasVosLiberabit Group Title

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

9. VeritasVosLiberabit Group Title

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..

12. natasha.aries Group Title

just kidding!

13. natasha.aries Group Title

i got it! haha i divided wrong

14. VeritasVosLiberabit Group Title

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

15. VeritasVosLiberabit Group Title

ok good job :)

16. natasha.aries Group Title

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 Group Title

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

18. VeritasVosLiberabit Group Title

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

19. natasha.aries Group Title
