On a slope with a constant incline of 20.0°, a car descends. When the brakes are applied, the car's speed decreases from 90.0 km/h to a complete stop in 6.00 seconds. Calculate the horizontal and vertical components of the car's acceleration during this braking process.

• A. a_x = -3.92 m/s², a_y = 1.43 m/s²
• B. a_x = - 14.1 m/s², a_y = 1.43 m/s²
• C. a_x = -3.92 m/s², a_y = 5.13 m/s²
• D. a_x = -14.1 m/s², a_y = 5.13 m/s²

Answer: (A)
