Answer:
false
Step-by-step explanation:
The kinetic energy of a crash is not "used up" in crushing the metal of the vehicle. In a crash, the kinetic energy is converted into various forms of energy, such as deformation energy, sound energy, and heat energy. The energy is not destroyed but rather transferred and dissipated throughout the crash. Crushing the metal of the vehicle is one of the visible effects of the crash, but it does not account for the complete conversion of kinetic energy.
