It takes a soccer player 3 seconds so reduce his speed to 3.1 m/s. what is the magnitude of his acceleration?

The magnitude of his acceleration is .

Explanation:

Final velocity of the player= v = 3.1 m/s

Initial velocity of the player = u = 0 m/s

Time taken  by the player = 3 s

Acceleration of the soccer player = a

Using first equation of the motion:

The magnitude of his acceleration is .

c. newton's third law of motion
