A car starting from rest accelerates at a rate of 8 0 m/s/s. What is its final speed at the end of 40 seconda? i have no idea what is if you know the answer, can you please answer it?

you have to organize the data. a= acceleration vi=inicial velocity vf=final velocity  t=time.

a=80m/s

vi=0

vf=?

t=40 s

the formula you have to use is:

vf=vi+a*t  (final velocity= inicial velocity plus acceleration times time)

Explanation:

I was the best one at my class, hope it helped

320 m/s

Explanation:  V initial = 0, V final= ?   Acceleration = 8m/s/s  t=40s
