What movement did the car make, moving from the rest position with an acceleration of 0.5 m / s in 10 s?

| V0 = 0 m / s.
a = 0.5 m / s2.
t = 10 s.
S -?
For movement with constant acceleration, and the path S traversed by the body is determined by the formula: S = V0 * t + a * t ^ 2/2, where V0 is the initial velocity of the body, t is the time of body movement.
Since the car starts its movement from a state of rest, its initial speed V0 = 0 m / s.
The formula will take the form: S = a * t ^ 2/2.
S = 0.5 m / s2 * (10 s) ^ 2/2 = 25 m.
Answer: the movement of the car during acceleration is S = 25 m.
