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, Negiect the mass of the wheels. Negiect the suspension

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?
