Just wanted to say a quick thanks to Steve and Damon, figured it all out, thanks guys, awsome!!!
physics
I gave the wrong answer at first. Sorry.
physics
Sorry the answer they have is 60.5 degrees east of of north or 29.5 degrees north of east. There would be two vectors right, so do you take the degrees from the resultant? Thanks Damon, I do not nothing about this stuff at all. The question says my answer should be found by dr...
