Answer:
This is what is meant by the concept of “net force.” the net force acting on a body is the sum total of all the individual force vectors acting on the object. When this net force is non-zero, we say the forces are unbalanced. When the net force is 0, we say that the forces are balanced.
Explanation:
They are similar because of their colour theyre differnt because there aint any silver
If the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.
<h3>
What is momentum?</h3>
The momentum of an object in motion is the product of mass and speed of the object.
P = mv
<h3>Conservation of linear momentum</h3>
The principle of conservation of linear momentum states that, the sum of the initial momentum must be equal to the sum of the final momentum.

Thus, if the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.
