        title: Exploding Asteroid
        name: Santiago
        name2: Savannah
      part1:
        ans1:
          value: The change in the momentum vector they determine for each piece of
            the asteroid before and after the explosion will be the same.
        ans2:
          value: They will both agree on how the kinetic energy of each of the pieces
            has changed.
        ans3:
          value: The momentum vectors they use to describe each of the two asteroid
            pieces will be the same.
        ans4:
          value: They will both agree on how the total kinetic energy of the system
            has changed.
        ans5:
          value: The final speeds they measure for the two asteroid pieces will be
            the same.
        ans6:
          value: The final velocity vectors they use to describe the two asteroid
            pieces will be the same.

## Question Text

{{ params.vars.name }} and {{ params.vars.name2 }} are both standing in their spaceships, each one moving with a different constant velocity.
They carefully watch and measure, from their two spaceships, an asteroid exploding into two parts. Select the correct statement(s).

### Answer Section

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.
