Greetings everyone! Thanks in advance for the help!
Two parts to the problem. For both parts it asks for the magnitude of the net force and the direction of angle from the X axis.
Part A:
Two forces, F1 and F2, act on an object at rest at a 90* angle. F1 = 30N, F2 = 11N, M = 9kg
F1


____F2___Part B:
F1/
./
/____ F2
Theta is 60*
Part A:
For magnitude, I got 31.8N.
Fnet = sqrt [ f1^2 + f2^2 ]
Angle: 24*Part B:
Magnitude:
Fnet = F1 + F2
F1 = (30N) cos 0 + (30N) sin 0 => (30N) 1 + 0 => 30N
F2 = (11N) cos 60 + (11N) sin 60 => (11N) 1/2 + (11N) 0.8660 => 15N
Therefore, Fnet = 45N
Angle: 16*
I really don't think I came close to the answers...but someone let me know, please!

The Attempt at a Solution
Part A:
For magnitude, I got 31.8N.
Fnet = sqrt [ f1^2 + f2^2 ]
Angle: 24*Part B:
Magnitude:
Fnet = F1 + F2
F1 = (30N) cos 0 + (30N) sin 0 => (30N) 1 + 0 => 30N
F2 = (11N) cos 60 + (11N) sin 60 => (11N) 1/2 + (11N) 0.8660 => 15N
Therefore, Fnet = 45N
Angle: 16*
