anonymous 4 years ago what is the accelaration of a ar that goes from 40 km/ hr to 80 km/hr in 2s?

1. anonymous

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

2. anonymous

I finished that one my self

3. anonymous

for this problem do i devide the multiply

4. anonymous

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

5. anonymous

$20m/s^2$

6. anonymous

I ma trying to find out the acceleration in seconds

7. anonymous

would it be squared?

8. anonymous

no

9. anonymous

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

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

12. anonymous

can we simplify that?

13. anonymous

yeah why not..

14. anonymous

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

15. anonymous

No it's asking the acceleration so acceleration

16. anonymous

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

17. anonymous

rvg what are you talking about

18. anonymous

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