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.

My guess is A you want the child to feel support and you don’t want the parents hanging around making that hard but you want the parents to know that you are doing your part. If you distract the child he or she will not learn and may feel upset that he or she didn’t know they left.
I think it is b, but i am not certain
They will weaken because they wont be used
