Assuming the constant acceleration, the covered distance is given by:
where "d = 10\\times10^3m" is the distance, "a" is the acceleration and "t" is the time.
On the other hand, by definition, the acceleration is:
where "v = 50m\/s" is the final velocity and stands for the intitial velocity (start from rest).
Substituting the expression for "a" into the first equation and expressing "t" , get:
Substituting the last equation into the expression for "a", obtain:
Answer. 0.125 m/s^2.
