A railroad car collides with and sticks to an identical railroad car that is initially at rest. after the collision, the kinetic energy of the system is "half as much as before". The correct option is (B).

What is kinetic energy?

Kinetic energy, which may be seen in the movement of an object, particle, or group of particles, is the energy of motion.

K.E. = 1/2 m v2

What is difference between kinetic energy and potential energy?

Potential energy is the energy that is held in reserve in a system or object as a result of its position or configuration. An object's kinetic energy is measured in relation to stationary and moving items in its immediate environment.
