In an inelastic collision where does the kinetic energy lost from the objects go? What kind of energy does the kinetic energy turn into?

In an inelastic collision, the kinetic energy that is lost can be seen from something such as a car crash. Thermal energy will be significant, in addition to sound energy.

The kinetic energy transforms because of the force exerted on the objects leading to friction and vibration.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
