What is the magnitude of the impulse on an 7.2 ball rolling at 1.2 when it bumps into a pillow and stops?

First of all the grammar in this question is atrocious. Second, this question can not be answered because there are missing 'given' facts. The ball is 7.2, in what type of measurement? It could be inches, feet, in metric and so on. The same goes for the ball rolling at 1.2, 1.2 what? Once again, inches, feet, in metric and so on. So the answer is 0 because there is not enough information to make a determination.

How does rolling reduce friction?
It may help to imagine a pair of gears. If the gears turn, then the teeth can intermesh. If, however, you fix one of the gears and attempt to move the other without turning it, or turn it without moving it, there's a problem: you're trying to push the teeth of one gear THROUGH the teeth of the other gear. Essentially the same thing is going on with rolling friction vs. static friction. Most objects don't have "teeth" like gears, but their surfaces are not perfectly smooth either; on an atomic scale, even if they're as smooth as possible, there are still "bumps" because the atoms can't be cut in half.
How is static friction and rolling friction similar?
They are both forms of friction. rolling friction occurs because two objects are rubbing against each other. under a microscope you would see that the two objects have bumps and these bumps run into each other, causing both objects to change velocity. thus rolling friction resists the relative motion of two objects. however, static friction occurs when two objects are pressed against each other and they have the same velocity, the microscopic bumps have time to sink in to each otherand creates a better grip than rolling friction. thus static friction resists any relative motion between two objects and is the reason why pushing a car is sudenly easier when it has some motion.
