Doc Brown has calculated his Delorean can accelerate at a rate of 2.52 m/s/s. How far away must he and Marty stand to allow the car to accelerate from rest to a speed
of 39.2 m/s?

The value  is  

Explanation:

From the question we are told that

   The  acceleration is

    The speed to attain is

Generally the time taken is mathematically represented as

=>    

=>    

Generally from the kinematic equation we have that

Here the initial  velocity is  zero i.e  u =  0 \  m/s (it started from rest)

So

=>  

the independent variable, or the one that is intentionally manipulated is the speed.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
