The wind exerts a force of 100N North on a sailboat, while the water exerts a force of 98N west on the sailboat. a)What is the magnitude of the net external force on the sailboat answer in units of N. b) How many degrees west of north is this net external force directed?
Pythagorean Theorem, trig
The Attempt at a Solution
So to solve part a I used a²+b²=c², 100²+98²=c² and I got 140.014285 N
Now I'm stuck on part b because when I draw the vectors, I have a vector going straight up(100N) and a vector attached to its tail going to the left(98N). I don't know which angle they are asking for.
