Debbie is an engineer who designs safety features to protect drivers in rear-end collisions. She has developed a new system that allows the front end of an automobile to bend or crumple during any head-on collision, thereby reducing the rate of deceleration experienced by the driver. The safety system is known as a front-end crumple zone. Suppose a rear-end automobile collision occurs between the two cars illustrated below. The orange car was waiting at a light with its brakes locked when the blue car collided with it from behind. The blue car had Debbie's front-end crumple zone system installed, which helped reduce part of the force of the collision.

Ответ:
A rear end zone crumple in the orange car
Explanation:

Ответ:
1. Potential energy is converted into kinetic energy since they are in motion.
2. As they slope down, work is done against the dissipative forces e.g; Air resistance, viscosity ( friction ). Hence energy is lost.
3. Different weights and heights at which they started sloping.
where mg is the weight.
h is the height moved
therefore, weight and height determines the potential energy.
