Asoccer player is running at 6m/s. he then stumbles over an opponents foot falling, and rolling to a stop. this took 4 seconds. what was his acceleration?

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.

as technology advances, new experiments often expose problems in accepted theories. c
