SUMMARY
The discussion clarifies that the weight of a car does not affect the "slide to stop" time when braking, as both inertia and deceleration force are proportional to the car's mass. The relationship is defined by the equations of motion, where inertia is represented as ma and the deceleration force as mgk, with 'm' being mass, 'g' the acceleration due to gravity, and 'k' the coefficient of friction. When equating these forces, the mass cancels out, leading to a constant deceleration 'a' equal to gk. This principle is fundamental in understanding braking dynamics.
