Asked by jenny
What are the a) x components of a verctor a in the xy plane if its direction is 250 degrees counterclockwise from the positive direction of the x axis and its magnitude is 7.3m?
b) the same question as above but for the y component of the vector a.
In the book it says that the answer for a) is -2.5m
b)-6.9m
I can't seem to get these answers. Can you help me?
Measuring the angle the way you specified:
xcomponent= Mag*cosTheta
Ycomponent= Mag*sinTheta
The book seems to be in agreement with this.
