When a speeding truck hits a stationary car, the car is deformed and heat is generated. What can you say about the kinetic energy of the system after the collision?

I can say that the kinetic energy after the collision is less than it was before the collision. I can say this with confidence because you've said that some energy was used to deform the car, plus there was energy lost from the system in the form of heat.

B. The kinetic energy of the system is partially used for deforming the car. ;

The kinetic energy of the system after the collision is less than it was before due to energy being transformed into heat, deformation, and sound. This type of collision is classified as inelastic, where kinetic energy is not conserved. The energy is not destroyed but rather converted into other forms, demonstrating the principle of conservation of energy.
