A 10kg mass has a force pointing in the east direction and another force pointing in the south direction 45 degrees from the east force |F1|=12 Nt, |F2|=19 Nt
a)total force vector?
b)mag of total force
c)direction of total force
F=F1 + F2
The Attempt at a Solution
a) The only thing that's confusing me really is what to do with the degrees. I'm guessing to find the total force vector you would do 12(cos theta, sin theta) + 19(cos theta,sin theta). I'm just having trouble deciphering which degree to use. As a guess, I would think its cos1,sin0,cos45,sin-45 respectively.
b)Once you find this vector, you add the squares of the two numbers and then take the sqrt of the total. I'm pretty sure this is correct.
c)I'm thinking the direction is asking for the degrees, so you would have to take the inverse of tan y/x.
I'm okay with b&c I think. I just need help on how to find the degrees
