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.
