Sally wants her car to accelerate faster than before when it could accelerate at a rate of 5 m/s2. Her car starts out with a mass of 500 kg, and in order to accelerate faster, she removes 150 kg of mass from her car. How much faster will her newly lightened car accelerate, compared to before she removed the 150 kg from her car? Assume the same net force is applied to cause the acceleration for both masses of the car.
