Copy the problem below into a text editor or word processor.
• This form accepts only text so a text editor such as Notepad is fine.
• You might prefer for your own reasons to use a word processor (for example the formatting features might help you organize your answer and explanations), but note that formatting will be lost when you submit your work through the form.
• If you use a word processor avoid using special characters or symbols, which would require more of your time to create and will not be represented correctly by the form.
• As you will see within the first few assignments, there is an easily-learned keyboard-based shorthand that doesn't look quite as pretty as word-processor symbols, but which gets the job done much more efficiently.
You should enter your answers using the text editor or word processor. You will then copy-and-paste it into the box below, and submit.

The equilibrant of a force is the force which is equal and opposite to that force. If two forces are equal and opposite, their x and y components are also equal, but the x and y components of the force are opposite in sign to those of the equilibrant.
The x and y components of a force are 2 Newtons and 3 Newtons repectively.
• What are the magnitude of this force and what angle does it make as measured counterclockwise from the positive x axis?
M = [sqrt] 2^2 + 3^2
M = [sqrt] 4+9
M = + - 3.6
= 3.6
Angle:
Arctan(3/2) = arctan(1.5) = 56.3°

• What are the components of the equilibrant force?
X = -2 N
Y = -3 N

• What angle does the equilibrant force make as measured counterclockwise from the positive x axis?
Arctan (-3/-2) = Arctan (1.5) = 56.3°
the equilibrant isn't at the same angle
note that the x component is negative, which requires that you add 180 deg to the arctan
