When an automobile crashes, the kinetic energy of the vehicle is converted to he

Question

When an automobile crashes, the kinetic energy of the vehicle is converted to heat, crushed metal, injury, and death. From what you have seen (in real life and in movies), consider two crashes, one at 35 mph, and another at 70 mph. Is it plausible that a crash of the faster automobile is 4 times worse? What other factors besides speed could affect the outcome of the crash? Airplane velocities are typically 600 mph except during take-off and landing, when they are closer to 150 mph. Does the kinetic equation explain why there are few survivors in an airplane crash? (Word limit: 500)

Explanation / Answer

no we cant say that it would be 4 time worse because other factor such as mass of the vehicle also matters.

aa heavy vehicle like truck is much worse than a fast moving bike. But if mass of system is same then we can say that at given condition it would be 4 times worse.

time of energy transfer is also a factor besides speed and mass.

If same amount of energy transfered in lesser time it would be much worse.

In case of airoplane we dont see collision so their velocity me not be the cause of deaths as if air forces opposing motion is not present so energy conversion is very slow. Its the height and explosions that take place is the main cause. Velocity may become a factor but not major.
