Answer:
The acceleration of the soccer player is
and it is decelerating.
Explanation:
Given that,
Initial speed of a soccer player, u = 6 m/s
Finally, it stops, v = 0
Time, t = 4 s
We need to find the acceleration of a soccer player. We know that the rate of change of velocity is called acceleration of an object. It is given by :

So, the acceleration of the soccer player is
and it is decelerating.
