In a video game, a ball moving at 0.6 meter/second collides with a wall. after the collision, the velocity of the ball changed to -0.4 meter/second. the collision takes 0.2 seconds to occur. what’s the acceleration of the ball during the collision? use .

-5 m/s²

Explanation:

Acceleration = change in velocity / change in time

a = (v − v₀) / (t − t₀)

a = (-0.4 m/s − 0.6 m/s) / 0.2 s

a = -5 m/s²

The ball decelerates at a rate of -5 m/s².
