Rear Raised Standard 0.6 m 0.4 m 1.3 m 1.6 m 1.3 m 1.6 m Car image from YouTube.com Newton's Laws (Rigid Bodies): In an attempt to make her car accelerate faster, a drag racer has raised the rear of her car to increase the centre of gravity by 0.2 m. The shift in the horizontal location of the centre of gravity is negligible. The car has a mass of 1600 kg and the coefficient of friction is 0.3. The car is rear wheel drive. The front wheels roll freely. Neglect the mass of the wheels. Neglect the suspension deflection. Assume the front wheels stay on the ground. What is the change in maximum acceleration as a percentage taking the unraised car as the reference?
