a car can accelerate from rest to 70 km/s in 7 seconds. what is the cars average acceleration. show your work

10km/s²

Explanation:

Given parameters:

Initial velocity  = 0km/s

Final velocity = 70km/s

Time  = 7s

Unknown:

Acceleration =?

Solution:

Acceleration is the rate of change of velocity with time.

It is mathematically expressed as;

      A =  

v is the final velocity

u is the initial velocity

 t is the time

       A  =   = 10km/s²

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

technology is the application of the knowledge gained by science.
