Answer:

Not possible

Explanation:

Suppose there's no external force, then the momentum must be conserved before and after the collision.

Since momentum is defined as the product of object mass and speed. This means that if after the collision, for both object to be at rest then the total momentum is 0.

But before the collision, only 1 is at rest, the other is not -> the total momentum is non 0 before the collision.

Therefor this is not possible with the law of momentum conservation.

Distance versus Displacement Worksheet
Umnica [9.8K]

when we find the distance we will add all the blocks so

distance = 6+6+4

distance = 14blocks

when we find the displacement we will add and minus too

As you can read he goes to the south 6 and to north 6 so he leave that place and back to the place again so the displacement is 0. and again he goes to the west 4 blocks so the displacement = <em><u>4blocks</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>west</u></em>
