Two vectors are shown. Which statement best compares the vectors?
2 answers:
Answer:
Vectors Y has greater magnitude than vector X
Explanation:
The attached figure shows two vectors. A vector have both magnitude and direction.
The length of vector X is less than vector Y. They both are pointing in opposite directions.
The magnitude of a vector is given by :
a = xi +yj
From the figure, it is clear that the vector Y has greater magnitude than vector X. Hence, the correct option is (B).

Explanation:
Mass of the ball: ]
Initial velocity of the ball:
final velocity of the ball: which is -30/100 of
=
Mass of the bottle:
Initial velocity of the bottle:
final velocity of the bottle: is unknown (to find)
<em>by using conservation momentum, which stated that the initial momentum is equal to the final momentum.</em>
<em /><em />
<em>so since the bottle is at rest firstly, therefore </em><em />
<em /><em />
<em /><em> </em><em>equation 1</em>
so now substitute into equation 1
<em /><em />
<em>collect the like terms</em>
divide both side by
Now substitute
