Isn't mass related to inertia? The larger the mass the more inertia. Acceleration is a change in speed or direction. It is easier to accelerate a smaller mass than a larger mass. I can be easily corrected, but according to Newton's second law of motion doesn't
acceration = force/mass? Acceleration and mass have an indirect relationship in that the
smaller the mass (inertia) the larger the acceration with the same force (force = m x a),
likewise, the larger the mass the slower the acceleration. If you have a car with 300 hp and 300 torque, the car with less mass will accelerate at faster rate.
With all that technical talk, I would put my money on the lighter car/with lighter brakes
accelerating at a faster rate. Let me know what you think?
