Answer: -1.5m/s^2
Explanation:
Initial velocity V1 = 14.0 m/s
Final velocity V2 = 5.0 m/s
Time taken = 6.0s
The car's acceleration = ?
Since acceleration is the rate of change of velocity per unit time
i.e acceleration = (V2 - V1) / T
Acc = (5.0 m/s - 14.0 m/s) / 6.0 s
Acc = (-9.0m/s) / 6.0s
Acc = -1.5m/s^2 ( the negative acceleration means the car is slowing down)
Thus, the cars acceleration is -1.5m/s^2
