Using the results of Question 1 that would apply if the collision were inelastic, compute (using Excel in the yellow highlighted box) the fractional kinetic energy loss during the collision. Express the "loss" as a percent. What became of the "lost" energy?

The fractional kinetic energy will be lost if the collision is inelastic. In inelastic collision, the kinetic energy is converted into other forms of energy.

The lost energy became heat and sound energy.

Explanation:

During inelastic collision, the kinetic energy of a moving object does not conserve. It changes into another form of energy such as sound energy and heat energy etc.

For example, when a moving car hit another car or wall etc, the kinetic energy is converted into sound and heat energy. This type of collision is inelastic collision.

the device is called “ rocket engine”

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
