Our atmosphere would be quickly stripped away, much like what apparently happened on Mars after its molten core cooled and solidified. The spinning Earth core is what helps create our magnetic field, without which means no Van Allen Belts, which mean solar radiation becomes more lethal than just sun burn

Answer:
4.09 kgm/s
Explanation:
Concept tested: Second Newton's law of motion
So what does the second Newton's law of motion state?
- According to the second Newton's law of motion, the resultant force and the rate of change of momentum are directly proportional.
- That is;
, where, mVf is the final momentum and mVo is the initial momentum.
In this case;
- Force = 12.8 N
- Initial momentum, mVo = 1.3 kgm/s
- Time, t = 0.218 seconds
Therefore; replacing the values of the variables in the formula;
we get;



Solving for final momentum;

= 4.09 kgm/s
Therefore, the final momentum of the box is 4.09 kgm/s
