I have been having a debate that a vector in the positive x-direction must not have a y component other than 0. What are the other opinions on this wording and other possible wordings to mean that a vector is on the same line as an axis?
My work found the resultant vector to be:Consider four vectors ~F1, ~F2, ~F3, and ~F4,
where their magnitudes are
F1 = 48 N,
F2 = 22 N,
F3 = 24 N, and
F4 = 50 N.
Let
theta1 = 150 degrees,
theta2 = -140 degrees,
theta3 = 20 degrees, and
theta4 = -63 degrees, measured from the positive x axis
with the counter-clockwise angular direction
as positive.
What is the magnitude of the resultant vec-
tor ~F , where ~F = ~F1 + ~F2 + ~F3 + ~F4? Answer
in units of N.
Can someone explain to me that "Note:"?(part 2 of 2)
What is the direction of this resultant vector
~F?
Note: Give the angle in degrees, use coun-
terclockwise as the positive angular direction,
between the limits of -180 degrees and +180 degrees from
the positive x axis. Answer in units of degrees.
