Homework Statement


Two vectors ahve magnitudes of 10 and 15. The angle between them when they are drawn with their tails at the same point is 65 degree. The component of the longer vector along the line of the shorter is:
A) 0
B)4.2
C)6.3
D)9.1
E)14


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
Any attempt at the solution? Is the 65 degrees assumed to be from the x-axis or is it not 65 degrees from the x-axis and just on the plane?
 
you need to show work b4 help is given ... you have 2 posts currently w/ no work, i doubt anyone will help you to the extent that you'd like.

what eqn do you think will be useful in this prob.?
 
One easy attempt at a solution would be to draw a picture. In this case, it comes down to simple trig. Hint: one of the numbers isn't used in the solution.
