## A.Y_swagger 3 years ago what is the accelaration of a ar that goes from 40 km/ hr to 80 km/hr in 2s?

1. gaara438125

don't you want to finish your other question first?

2. A.Y_swagger

I finished that one my self

3. A.Y_swagger

for this problem do i devide the multiply

4. gaara438125

are you trying to figure out the acceleration in the form of km/s or km/2s?

5. rvgupta

$20m/s^2$

6. A.Y_swagger

I ma trying to find out the acceleration in seconds

7. gaara438125

would it be squared?

8. A.Y_swagger

no

9. Miyuru

So it's simple. Do u want an physics equation or shall explain it in maths.

10. A.Y_swagger

11. Miyuru

Ok then do like this 80-40 km/h 40/2s

12. gaara438125

can we simplify that?

13. Miyuru

yeah why not..

14. gaara438125

didn't know if swagger wanted for 2seconds or 1 lol

15. Miyuru

No it's asking the acceleration so acceleration

16. rvgupta

sorry i did not see the units $5/9m/s^2$ should be the right ans

17. gaara438125

rvg what are you talking about

18. Miyuru

It would be.. $\frac{ 400 }{ 72 }ms^{-2} = 5.5 ms^{-2}$
