<span>The normal force is the support force exerted upon an object which is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. The normal force in itseñf comes from the third law of Newton as a reactive force</span>
Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
The answer is <em>Compressional Stress
</em>
In geology, stress<span> is the force per unit area that is placed on a rock. ... This is called confining </span>stress<span>. Compression squeezes rocks together, </span>causing<span> rocks to fold or fracture (break). Compression is the most common </span>stress<span> at </span>convergent plate boundaries<span>.
I hope this helped!! Have a great day :D</span>
initial momentum of 2 kg blob is given as

here we have



initial momentum of 3 kg blob is given as

here we have



So initially 2 kg Blob has most momentum before they collide
