Acar starting from rest (i. e. initial velocity = 0.0 m/s), moves in the positive x-direction with a constant average acceleration = 3.1 m/s2 for 7.9 s. what will be its velocity at that time.

Final speed of the car, v = 24.49 m/s

Explanation:

It is given that,

Initial velocity of the car, u = 0

Acceleration,

Time taken, t = 7.9 s

We need to find the final velocity of the car. Let it is given by v. It can be calculated using first equation of motion as :

v = 24.49 m/s

So, the final speed of the car is 24.49 m/s. Hence, this is the required solution.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
