.How does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph?

The overall kinetic energy of the 60mph car is greater than the overall kinetic energy of the 30mph car. Because of this, it takes a greater force to stop the faster car because it has greater amount of kinetic energy (aka the amount of force needed to overcome the momentum of the faster car is larger).
