Question

Berapa resultan nya??? pliss jawab

Answer 1

F1x=20 cos 90
=20×0
f1x=0 N
f1y=20sin 90
=20×1
=20 N
f3x=24 cos 30
=24×1/2√3
=-12√3N
f3y=24 sin 30
=24×1/2
=-12N
f2x=20 cos 60
=20×1/2
=-10N
f2y=20 sin 60
=20×1/2√3
=10√3 N
R x=0-12√3-10
=-10-12√3
Ry=20-12+10√3
Ry=8+10√3
Resultannya=√(10-12√3)²+(8+10√3)²
=√100-144×3+64+100×3
=√-332+364
=√32
=4√2 N
sekian

Answer 2

F1=20N
F2=20.cos60 =20.1/2=10N
F3=24.cos60=12
setelah itu tinggal kamu masukkan rumus utk resultan
