Sketch a vector representing a 10 Newton force which acts vertically downward. •Position an x-y coordinate plane so that the initial point of your vector is at the origin, and the angle of the vector as measured counterclockwise from the positive x axis is 250 degrees. This will require that you 'rotate' the x-y coordinate plane from its traditional horizontal-vertical orientation.
answer/question/discussion:
force vector is vertical and is along the negative vertical axis , will rotate until it gets to 250 degrees

• What are the x and y components of the equilibrant of the force?
answer/question/discussion:
x component: 10 N * cos(250 deg) = - 3.42= + 3.42
y component: 10 N * sin(250 deg) = -9.40= + 9.4
