Question

A system of particles is known to have a total kinetic energy of zero. What can you say about the total momentum of the system?

Answer 1

The answer is "Momentum of the system is zero".

Step-by-step explanation:

Kinetic total energy
`= \sum 0.5m_(i) v_(i^2)` Where I'm different particles. Every particle should be 0 velocities (As v is in the square) for total kinetic energy to be 0.

Total momentum
`= \sum 0.5m_(i) v_(i^2)` As all the particles have a speed of 0, as shown above, the momentum is 0. Thus, the total system momentum is 0.

It's value:

`\to KE=0 -> V=0 -> p=0\\\\\to P=mv`

Answer 2

The momentum of the system would be zero. A further explanation is described below.

Step-by-step explanation:

• The quantity of direction of travel which always takes place throughout something which moves or perhaps the start forcing that continues to moves something forward to maintain its movement, recognized as Momentum
• As momentum varies depending on velocity, these were quantified by something that also relies mostly on direction including its body's natural movement.

Therefore the correct answer would be the one mentioned.
