Answer to Question #157352 in Physics for Raky Barry

Question

Two forces F1 and F2 act on a particle. F1 has magnitude 5N and in direction 030° and F2 has magnitude 8N and in direction 090°. Find the magnitude and direction of their resultant. [ 11.36N; 067.6°

Answer 1

$F_{net}=\sqrt{(5\cos30°)^2+(5\sin30°+8)^2}=11.36(N)$

$\tan\alpha=\frac{5\sin30°+8)^2}{5\cos30°}=2,4248\to \alpha=67.6°$ . Answer
