Final answer:
To accelerate at a rate of -10 m/s² while driving a car, you would apply the brakes to slow down.
Step-by-step explanation:
If you were driving a car and wanted to accelerate at a rate of -10 m/s², you would apply the brakes to slow down. Acceleration is the rate at which the velocity of an object changes over time. A negative acceleration means the object is slowing down or decelerating. By applying the brakes, you are increasing the negative acceleration, which will slow down the car.
