Answer:

what is the kinetic energy of a car when it suddenly stopped because of a stray dog crossing the road

Explanation:

When you try to stop the car, the car does not stop immediately. "Stopping distance" refers to the distance the vehicle travels while the brake is operating. By definition of work (work = force x distance), the car's kinetic energy is equal to the braking force multiplied by the stopping distance

When a force is applied to the brakes of a vehicle, there is work done on the friction between the brakes and the wheel. This reduces the kinetic energy of the vehicle, slowing it down and causing the temperature of the brakes to increase

These bits of energy go into heating the road, the surrounding air, and various spinning parts in your car. But the vast majority of the kinetic energy is converted into heat by your brake pads when you stomp on the brakes
