Ximena and Savannah are both standing in their space ships, each one moving with a constant (but different) velocity. They carefully watch and measure, from their two space ships, an asteroid exploding into two parts. When they compare their final numbers, which of their numbers will agree?
Select all the choices that apply.
Note: You will be awarded full marks only if you select all the correct choices, and none of the incorrect choices. Choosing incorrect choices as well as not choosing correct choices will result in deductions.
They will both agree on how the internal energy of the system has changed.
The final speeds they measure for the two asteroid pieces will be the same.
They will both agree on how the TOTAL kinetic energy of the system has changed.
The CHANGE in the momentum vector they determine for each piece of the asteroid before and after the explosion will be the same.
The final velocity vectors they use to describe the two asteroid pieces will be the same.
The momentum vectors they use to describe each of the two asteroid pieces will be the same.
