A speeding truck travels in the positive x direction. It hits a car traveling in the positive y direction. The vehicles are deformed and travel together at an

angle with the positive x-axis. What can you say about the kinetic energy of the system after the collision?

Kinetic energy of the system is conserved.

B.

Kinetic energy of the system is partially used up in the deformation of the vehicles

Kinetic energy of the system is unrelated to the deformation of the vehicles.

C.

D.

Kinetic energy of the system is completely transformed to heat energy

The right one is b I believe

Mason Kemp · Answer 2

B. Kinetic energy of the system is partially used up in the deformation of the vehicles.

Explanation:

In an inelastic collision, momentum is conserved, but kinetic energy is not. Kinetic energy is lost as heat or lost in the deformation of the objects.
