Answer:
[tex]p_a=p_b[/tex]
Explanation:
Here, there are two blocks of mass 1 kg and 3 kg that are connected with a spring and nothing else is attached to the blocks.
One of the blocks is pulled and released. Since no other forces are acting the momentum is conserved so the magnitude of each block will be equal.
The velocities will be different as the mass of the block are different.
[tex]p_a=p_b[/tex]
