The additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1
<h3>What is momentum?</h3>
Momentum can be defined as a scalar quantity that involves the multiplication of the mass of an object by its velocity.
In Physics, the momentum of an object such as a block, is calculated by using this formula;
Momentum = mass × velocity
In conclusion, we can deduce that the additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1.

The best translation of the following sentence "as for me, i don't know" we have that will be "por mi parte, no sé".
This will be the correct translation because when we look at the translation of the other options we have that they correspond to :
- "para siempre, no sé" wil correspond to "forever i don't know"
- "para que sepas, no sé" will correspond to "just so you know, i don't know"
- "por ejemplo, no sé" will correspond to "for example, I don't know."
In this way, the translation that best suits is "por mi parte, no sé".
