F1x = F1. cos60
F1x = -20. ½
F1x = -10 N(bernilai negatif karena arahnya negatif sumbu x)
F2x = F2. cos 60
F2x = -30. ½
F2x = -15 N
Komponen Fx
Fx= F1x + F2x
Fx = -10 + (-15)
Fx = -25 N (arah kiri)
komponen Fy
F1y = F1. sin 60
F1y = 20. ½√3
F1y = 10√3 N
F2y = F2. sin 60
F2y = -30. ½√3
F2y = -15√3 N
komponen Fy
Fy = F1y + F2y
Fy = 10√3 + (-15√3)
Fy = -5√3 N (arah bawah)
semoga membantu, semangat belajar fisika :)
