Seed Question 19-2

course phy 121

--------------------------------------------------------------------------------

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:

I have sketched this and am trying to figure out by the last sentence above if I'm supposed to be focusing on a 70 degree angle or the 250 degree one.

#$&*

What are the x and y components of the equilibrant of the force?

answer/question/discussion:

sin 250 = -.93

cos 250 = -.34

When you multiply by 10 you get -9.3, -3.4
