Assuming you're working in a 3D cartesian coordinate system, i.e. each point in space has an x, y, and z coordinate, you add up the forces' x/y/z components to find the resultant force.
Answer:-2.61 m/s
Explanation:
This problem can be solved by the Conservation of Momentum principle, which establishes that the initial momentum
must be equal to the final momentum
:
(1)
Where:

(3)
is the mass of the first car
is the velocity of the first car, to the North
is the mass of the second car
is the mass of the second car, to the South
is the final velocity of both cars after the collision
(4)
Isolating
:

(6)
Finally:
(7) This is the resulting velocity of the wreckage, to the south
The particles vibrate against each other in a soild state........i think
A microscope is used for the purpose of magnification of an object which is usually very minute - so much so that it is not easy to be seen with the naked eye. If a mount slide contains the word <em>lens</em> which is easily readable with the naked eye and if this slide is kept under a microscope, the text will appear:
- From left to right that is in the same original direction as it was positioned on the slide.
- Highly magnified which may make it illegible to be read using the microscope.
