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 kinetic energy in the faster case is 4x as much. the brakes must do an amount of work that is equal to the original kinetic energy. the brakes exert the same force in either case, so the distance will be 4x as long for the faster case. Hope i helped :)

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.
