Momentum for a system can be conserved in one direction while not being conserved in another. What is the anglebetween the directions? Give an example.

Respuesta :

Answer:

90°

Explanation:

The angle will be 90° when momentum for a system can be conserved in one direction while not being conserved in another.

The example can be

If we apply force on an object horizontally in west direction, then as in other direction south or north we cannot apply the principal of momentum conservation.

The angle between the two directions will be 90°

If we consider a scenario where object A is launched at a particular angle as shown in the image below.

Then, we can resolve the forces of the object into two perpendicular components.

i.e.

  • into y-axis and x-axis

Taking the acceleration along the horizontal x-axis, acceleration = 0. As such the total momentum in the x-axis is constant and the change in momentum will be zero.

i.e.

[tex]\mathbf{\Delta _P_x = 0}[/tex]  

In the vertical y-axis, there is an influence of gravitational acceleration acting on the system.

As such,  [tex]\mathbf{\Delta _P_y \neq0}[/tex]

Therefore, we can conclude that the angle between them is 90° since the force along the x-axis and y-axis are perpendicular to each other.
