Many cars are filled with an air bag. In a collision, the air bag inflates and reduces the effect of the impact between the passenger and the dashboard. In a test of the air bag, a heavy ball is used instead of the passenger. The car is travelling at 14m/s when it hits a wall. The air bag inflates and the ball takes 3.0 s to come to rest. Calculate the average deceleration of the ball.
