Answer:
=6.5%
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

If you illustrate the problem, you will somewhat come up with the figure shown. The missing value is the hypotenuse of the right triangle. Using the pythagorean theorems, the value is determined to be
x = √(0.7^2 + 2.4^2)
x = 2.5 km
2.5 km is the magnitude of the distance. If you want to incorporate the displacement, the answer is reported as 2.5 km, southeast. The direction is determined from the starting point to the endpoint.
